Progressions?
I hope by "Progressions" you mean betting ramp. If not, please read the info on Progressions in the BJ Reference section ASAP.
With your trip bank, you could be wiped out in one or two sessions, and realisticaly, it is likely to happen. Play the fewest number of decks with the lowest minimum bet you can find. Don't play during negative counts and if you lose count, take a break or quit.
Read all the articles in the BJ Reference section on this site and any of the books reccomended (and sold) by this site- they are solid and not based on Voodoo, or unscientific "systems".
No offense intended, but from your questions, it sounds like you need to put in more time studying, and building a bigger playing bank. Take it easy at the tables- it is easy to get overwhelmed and overdo it. Take frequent breaks and just make this a feild trial and not a $600.00 practice session.
