No problem, you sound like a great player looking for other great players - it will be easy to find but tough to join them, especially just before a big patch like 5.2 - what those guilds will have is players they have played with before who they are know are good returning to the game and taking up raiding spots.
I'd say your best bet would be to find a good guild that is moving from ten man or mulitiple ten man to 25 mans for the thunderforged stuff, or to wait a bit into 5.2 for the first bit of burnout to bite, whereupon you can grab a seat at the top table.
Hope that helps, it's just my thoughts on it.
