There's an excellent care sheet. Read through it first, then if you have any other questions, please feel free to ask.
I'd start with rattling off what you need, but sometimes it's best to have a care sheet to refer back to. 
Posting pictures is easy... if you use Photobucket, they've got the "IMG" code listed under your picture, just copy it and past it here. It basically looks something like:
[img.]http://www.wherevermypictureislocated.com/snake.jpg[/img.]
But without the . that I put in there so it would show the code.
