Anyone with rooting knowledge??

I am wondering if someone can maybe IM with me for help with rooting. I have rooted my phone I know that because apps for rooted phone work. However, I can not do a recovery. I am just running into all kinds of problems. Grrrrrrrr. I dont know what wrong. If I hold down the home + power button I just get this screen with a (!) that doesnt go away and I have to pull the battery.

I would really appreciate the help
