Only a brief answer here as I haven't much time atm (sorry!) :
Track 2 mismatch will be down to you using a newer version of EAC (at some point in it's version's - can't remember when off the top of my head & I'm not at home so can't easily check - the detection changed), track 52 (ie. the last track) suggests that your cd-rom drive can't overread into the lead-out, which is required on a lot of discs (Sega in particular).
I think (from memory) the version of EAC used on the current rips was v0.95 pb5.
