Airlines:
I suggest searching these 3 links, and after you find the flight you want, then check the airline Website itself to see if it's cheaper. Using these links is usually cheaper than using the convention's airline discount. Compare, compare, compare.

Travelocity
QIXO
Orbitz
Farechase

Airlines/Misc:
SeatGuru lets you know what are the good seats and what to avoid.

Lodging:
If you're in shock from looking at the convention hotel prices, check this. No rule says you have to stay at a con hotel.
