I don't remember where they came from, but I've got several reasonable explanations of the NMEA strings from a gps - quite long, obviously, so I won't post it directly, but email me and I'll send them out. They were public domain as far as I know.
As far as hooking it up, the most standard NMEA stream is a one-way (GPS->AVR) uart at 4800,n,8,1, almost all gps's will put that out one way or another. Most of the uarts are TTL-level, so you usually hook them right into the avr. I like the Trimble Lassen devices, myself. A bit pricey in singles (~$50), but very compact, and at least you can get them in singles - alot of the Sirf and Motorola stuff starts at 10k pricing.
