You asking these things takes no time at all; well, about half a second to think of them.
What I will say at this point is that this is a good example of where planning helps- if you had checked this out in advamnce you could have kidnapped a sales guy first. It's not a disaster because you'll get out of here soon but stakes get higher later, and if you want to pull one over the Jedi then good planning is your best friend.
If you want to know why Kuylen didn't do all the planning, it's because he can't be bothered with the details, he leaves them to you.
Takes more than clothes, Rex...
Sadly, I think the technical complexties of impersonating a sales staff guy are beyond the scope of your templates. Galder can kill and Takuan is greatr with the Force but you need someone like Quam for in-depth stuff like that. So try looking at the other solutions- finding the right trick with the droid or finding al alternate method of moving the drives.
