What's a stripper squadmate?
I assume someone that removes protection from enemies?
capn323 do u like Stasis as the bonus power for an Adept?
Miranda and Samara 
But seriously, squadmates with a power that has an AOE protection strip power (Overload, Incinerate, Area Reave up through level 29). Rank 3 / Unstable Warp can strip basic barriers, but is single target only.
It is usually simplest with adept to have at least one squadmate with the ability to instantly strip protections from the common enemies on the mission. Miranda can work for this. If you go Garrus / Miranda, then you can get into a rhythm where Garrus uses Area Overload to strip shields, Shepard uses AOE lift power, and Miranda detonates. Of course you can mix this up, if you don't necessarily need warp explosions, or you are early game before either has Overload evolved to Area, it makes sense to have them both use overload on targets while Shepard ragdolls / CC's them. Ragdolled targets get a "100%" damage taken bonus, and can't shoot back while they are ragdolled.
Mordin works well on Blood Pack or Collector missions, as already stated above. Incinerate is a good power, the best anti-armor power in fact, and is not horrible against organics who have weakened shields.
Tali wouldn't be my first choice as a squadmate, but you can get away with her. At recruitment she is specialized to nearly completely and anti-synthetic squadmate, especially since Combat Drone's cooldown is so long it isn't all that helpful on organic missions (most missions). After her loyalty mission, you can get the area evolution of Energy Drain, which will make her a lot more useful for an adept.
1 pt Stasis is the best bonus power for an Adept. It is arguably the best bonus for every class, but I like it on the biotics. Slam is ok to start with for guys on PC who can't take Stasis at character creation, and isn't a bad choice in its own right up through when you can unlock Pull.
Oh man, guys I need help! At the end of the Kasumi mission - with the damn gunship. I keep dying!!! Like, I'll fight off 4 waves of dudes with her, but then I just get overwhelmed. Help!!! So I'm Biotic and I have Kasumi only to help...
The trick with Kasumi's mission in general is to get Kasumi leveled to Rapid Shadow Strike, and order her to use it when she will certainly kill the target and get the cooldown bonus. The more time she is in cloak, the more time she is invulnerable, and her survivability go up.
For the gunship fight, the first wave is easiest at the low cover near where you start. Shepard should concentrated on defense stripping (warp or pistol for loki armor, smg for shields), and send Kasumi to Shadow Strike the weakened targets. It helps to order Kasumi into cover at the end of each strike so she doesn't go somewhere strange.
After that, the easiest spot is near the high crates / truck to the left of where you start since you can use it to block fire from the gunship nearly completely and engage the troops. After Kasumi sabotages the shields, then you can try to use pistol on the gunship in between waves to kill it. I have examples of soldier and vanguard, but none of adept, but this should work regardless of class, given Kasumi's powers (which is probably just Shadow Strike at this stage of the game).
