Questions about Stock 2.1 root....

[ecsnead69]

I am rooted running Pete's stock 2.1 ROM and I have a few questions for anybody that will lend an ear.....

1. Are there any kernels that will run on this ROM that can be OCd?
2. Does this support Apps2SD?
3. Where are the clockwork backups stored?

Another question.....

4. What is the best app/Apps for managing the root, changing icons for everything... basically anything that pertains to files, folders, and apps.

I am a relative noob, so be gentle and thanks for any info and help you can give me!!!!
