Thanks for the replys, at least I know a little bit more.
Yeah, hopefully when I go next week my brother will come with me, he has been playing for a few years and should be able to guide me. Also I take it the people at the shop will be able to help me choose something as well?
I'm not wanting to get a really cheap guitar, something thats not too expensive (under £200) and is half decent and last a few years, until I want to buy a better quality model.
In terms of an amp, my brother has one of those so I'll probably just be able to plug my guitar in and use that.
