Whew...fairly wide open request there. I'll try to offer some help.
First, there are lots of threads in the history of this forum that ask the same question. If you have some time, just use the 'search' function and be somewhat diligent and you'll find tons of detail if you don't feel like waiting for responses to this thread. I'd start by searching 'noob mic' in the microphones forum or something close.
Specific responses will depend specifically on your budget. You say you're on a limited budget, so I usually give the same response to that situation...one of the best sounding mic/preamp combinations for the money is the Church Audio CA-14 mics running into the Church 9100 preamp. You'll need about $250 to $300 for new, but the sound is outstanding for the money.
Since you'll be recording Phish from the section, you will want directional mics to keep the crowd noise minimized. Omni's pick up sound in all directions and since there's no need to record the drunken masses behind you, the cards will work best. In the case of Church, the CA-14 are available in both omni and cardiod model.
If you're looking for full-bodied mics, you also need to consider that you'll probably need a preamp. Cost is starting to go up now. There are plenty of entry level mics in the $200 a pair range and there are tons of high quality sounding modded UA-5's in the Yard Sale right now for $250 - $300.
Personal opinion though is these rigs don't sound nearly as good as the CA-14, plus there's more gear to lug in.
Personally, I'd sell your Tapers section tickets for a small premium (since they're taper tickets) and use the extra money to buy the CA-14 setup.
Then I'd turn around and buy tix that get you really great seats and use the CA-14 rig to tape from there.
In general, for a Phish show, I think the only real advantage you have in having a Section ticket is that you're guaranteed to get your gear in the door (and of course that you can fly your mics along with everyone else.)
But if you have a CA-14 rig, you might not need to worry about having your gear checked at the door and you can put the mics up high enough wherever you are to get a good recording.
My thoughts anyway.
