The problem I see with the gear packages is that based on what "role" you choose, you stand a chance of making out like a bandit in terms of starting gear, especially the Special Forces package.
I don't see this as being a role based option, too much, if your pilot is special forces then he gets the same gear as everyone in the group. Perhaps the snipper gets a slightly better rifle or the medic a handful of stims more than he. I also envisaged the fixed gear package would replace the 500cr and each players would just get his d100 pocket change.
The 500cr probably works best if you start in the thick of it. You grab what you can and head to the escape pod.....
As a GM I would ask my players how they would like to play the starting gear.
As a player I like the 500cr myself. I trust the GM will want his campaign to last beyond the first hour and he will make it hard and exciting to play for a session or two.
