Coby,
my rear brakes squeel too. I don't mind them anymore, but what you can do is use some 600 grit sand paper and lightly sand down the pads. On the rotor, get some alcohol and use a rag and wipe the rotor to take the glaze off. This has worked for me but eventually came back. I think it is because the brake pads need to be upgraded. As far as lock out, a lot of high end forks have a little give when they are locked out so i dont think you have anything to worry about.
