You need not have created so many partitions because it is going to hurt you now when you have to chroot. :)

Apache running under chroot means lot of things. OpenBSD has done it by default and it means that all the files that users host have to be under the chroot. All the DSOs have to be accessible as well.

chrooting ftp or sftp is not much trouble. I think a simple google search will tell you how to run sftp under chroot. I would suggest that along with chrooting ftp.

mysql should not give u much trouble but then I never use it. 

I am a postgresql guy...

Best of luck!
