I can recommend the Rough Guide to Egyptian Arabic as a useful phrasebook to take with you. Most of the 'teach yourself Arabic' things around are Modern Standard Arabic rather than the Egyptian version. Although there used to be a book/tape combination called 'Colloquial Arabic of Egypt' by Russell McGuirk - not sure if it's still in print, and I haven't used it before travelling, so not sure how useful it is!
BTW - I think the phrase for 'there is no money' would be pronounced: mafeesh floos
