My guitar wont stay in tune.

With Bigsbys and guitars that are susceptible to going out of tune, if you give the bar a little tug after using it it will return strings to pitch where sometimes they don't fully. Just get used to it as part of your technique and it could help, but s

This place is painful sometimes.

OP hasn't got round to putting new strings on it yet and he's being told to buy new parts for the trem, a new nut, and new tuners. 

First thing to do @Kerplunk is to put new strings on it. String it properly (watch the videos above) and make sure you stretch them in. New strings will go out of tune a little bit at first but they should soon stabilise.

If new strings doesn't fix it then you can begin to think about whether it needs a setup or whether more drastic measures are needed. Don't go throwing money at it without trying the simple things first. 

Well said. Think this place is bad? You should try The Gear Page!

In this order:

1. Proper stringing
2. Proper string-stretching
3. Nut 
4. Other obscure stuff

is usually how tuning stability problems pan out. Although it can be hard to admit that your stringing technique isn't solid
