To everyone,
Action points don't carry over from level to level. If you have any left over when you level, they disappear. Action points are calculated as 5 + 1/2 your hit dice + 3 from heroic spirit if you took it. So everyone should have 7 to start the module with and when you level up to 6th you will start that level with 8, except Hightower who will start next level with 7.
renau1g,
Fenwick's sheet said he had 40 action points which is a bit more than you should have.
Your feat selection seems odd:
I wasn't sure Spellcasting prodigy was in 3.5, if it is I'm sure you took this as your first level feat right?
Maximize spell will require you to use a fourth level spell slot, which you won't get until 8th level as a sorcerer. I'm unclear why you took it now
