Hey robeddie and welcome to the world of real money poker! 
Texas Grab'em only works for PartyPoker, so depending on what you plan on playing I would suggest some different programs.
Equilator: For calculating ranges and playing around with Equity is a definite must have sooner or later
PokerStrategy Elephant: Has the same functions as Grab'em but actually works for PokerStars. Also records all of your hands, and opponents hands - so while still being in Alpha testing already a powerful program: http://devblog.pokerstrategy.com/
If you are planning on playing SNGs I would definitely advise the ICM trainers 
Otherwise have fun reading the articles, watching videos (perhaps visiting some coachings) and clearing up that bonus!
Best regards and good luck at the tables,
