[hands her some gray sunglasses, so the baddies don't key on her lovely blue eyes.]

Good idea! But what if they notice the reflection/glare from the sunglasses? Or what if it's some sort of alien race that doesn't see at all and instead tracks by scent, sound, or sensing heat or movement?

Whatever she's up against, hopefully that blaster is up to the task...

Since it's sunglasses, they could just be made in matte gray. The lenses would just need to be clear enough to see without significantly altering vision, so it wouldn't be too hard to give them anti-reflective properties.
If the creature is not dependent on visual detection, then one would need a setup to help counter what it does use, if possible. Xer, for example, has no eyes and uses a combination of echolocation and electrosensory to sense the environment. Granted, he's fused into Rex-57, who does have more conventional senses. But it's hard for Xer to actually make sense of Rex's senses, and vice-versa. This is why neither typically tries to control the other. It gives them both headaches. It's easier to give Xer sensory overload than try to out-stealth him.

So, perhaps that could work. Shoot a flare gun (or plasma bolt) into a heat-sensing alien's face (or wherever their sensory is). Carry various types of stink bait to nauseate scent-based trackers. Have a music player with good speakers and Slim Whitman to explode the brains of sound-sensitive aliens and generally hurt the ears of everyone else. Something like an EMP emitter or other high-electric output device for electro-sense. Movement, have a few deployable drones to distract the whatever, so you can shoot them in the weak spot. Think a bit like how Batman typically caries a utility belt with stuff like kryptonite in it.

I do have an updated portrait of her here, where her design has been updated a bit to both reflect updates to the Starfarer species and her role as a jack-of-all-trades sort of adventurer, including goggles and a bandanna that can be used as in impromptu dust mask.

I do like the idea of a utility belt, especially for a character of a race that's already evolved to for lateral thinking and problem solving--less about having specialized equipment for every scenario, and more for carrying items that might be generally useful in whatever tasks she might find herself performing, combat or otherwise. I suppose in her case it would really just be a fairly standard tool belt, stocked with tools and commonly used small hardware items, the sort of things any resourceful individual could use to craft a variety of useful items provided the immediate environment can contribute some extra materials to work with.

I also made some updates to the design of the typical Reva blaster pistol, which can be seen here (second pistol in the top row, next to the Dominion infantry blaster). I find that plasma-based blaster pistols have some interesting potential in terms of damage-dealing and secondary attributes--their damage type would primarily be heat-based, probably considered "fire" damage in most conventional elemental-based damage classification systems, but I can also see it dealing a small amount of "electric" damage as a nifty side effect depending on how the plasma bolts are energized. Add in how plasma glows, and how the projectiles are generally larger and slower-moving than most bullets and other similar kinetic projectile, and the blaster can be used to distract motion-sensing and heat-sensing predators, perhaps distract those that tune in to electromagnetic waves to track prey, or she could simply shoot a hostile creature in the face (assuming she can determine what passes for a "face", it can be tricky to tell on some creatures) to blind and possibly kill it!

That, and I'm sure she knows at least three ways to convert the power cell for the blaster into an improvised explosive device, assuming she has a spare or two she's able to part with--use it directly as a sort of short-range plasma grenade, put it in a container with some screws and bolts to form a sort of fragmentation grenade, or combine it with a tripwire to make some sort of improvised mine. Most industrial settings also feature conveniently placed containers of flammable, explosive, or otherwise volatile substances that could be combined with the aforementioned "mine" configuration to deal some serious damage, too!

The exact nature of most plasma stuff in fiction is often hand waved, but yeah, the more serious looks at it is that plasma/fire is a conductor. As such, it wouldn't be too hard to use a lower-power EM/Railgun concept for delivery of plasma/fire bolts. Basically, magnetize the plasma shortly after creating it and use the EM/Railgun system to send it downrange. Typical reason it's slower moving is so that it stays cohesive. Too much force and you've not got a plasma bolt, but more of a cloud of plasma shot, which may dissipate faster and not be as effective. Logically, "shot, bolt, and stream" should be functions of any good variable use plasma gun. Shot would be good for your typical shotgun-type scenarios, or lighting a campfire. Bolts are typically your multipurpose round. Stream is typically overlooked, due to the fact that flamethrowers are considered a war-crime in our reality, but would be an effective method of dealing with swarms/boss monsters or destroying buildings.

As for utility stuff, thermite is surprisingly simple. Just carry a jar of aluminum powder from a hobby shop and find some rust.
