One option no one has tossed out if you don't need lots of padding: the blue roll pads. I use them for most all of my camping. Finally bought an inflatable, because I didn't want to eat up the space in my plane luggage, but the blue rolls are cheap and effective for me.

Moosejaw outlet has a few Marmot 2P tents in the mid $100's right now.

Sleeping bag, only thing I can suggest is that you figure out what temps you'll be using it in, and get one 15-20F lower than those expected temps. I use a 25F for Michigan summers, where the temps can easily get down in the high 40s/low 50s. If it is warmer, I just leave it unzipped. I haven't seen too many truly quality bags in temp ratings much higher than that either.

Also, if you have a Gander Mountain around you, they are all liquidating right now, you may be able to grab a deal on a bag and pad.
