1. Do you have to send a photograph along with you SAE and If so where can you get them?
You don't have to, but if they haven't got any of their own to hand it will give them something to sign and send back. It also gives you a choice of picture, which is handy if there's a particular one you like. They can always send their own instead, or as well, which some do.
I always send a pic, unless I know that they send their own (look at the feedback on here, it'll soon give you an idea of signing habits).
Google images is your friend (look for large images and crop to the right ratio using a picture editing package - otherwise the printed results can end up a bit strange). I get them printed at a very large supermarket chain, beginning with T. If there are any copyright marks on the pictures you're using, either remove them or use a different picture. I upload them through their website and pick them up a few hours later.
A simple rule of thumb I find useful: if I'm getting 10x8s printed, resize the picture and look at the finished result at about 1000 x 800 pixels at a ratio of 1:1 and ask if it looks good at that size and resolution. The same works for 8x6 resized to 800x600, 7x5 resized to 700x500 etc. If it doesn't then find another picture, or stick a great big border on, because if it looks grainy and pixellated the end result will be rubbish.
2. Will a 2nd class stamp (british) be ok to send an a4 envelope to a british address?
A large letter 2nd class stamp will do it, as long as it weighs less than 100g.
