What you're really asking for is read-protection on your filesystem -- which, unless you do full-disk encryption, you're not going to get.
The problem with encrypting folders and/or individual files is that, before you want to use them, you generally have to decrypt them. Somewhat of a pain if you use these files daily.
When you encrypt the whole disk, you have to provide the credentials BEFORE the disk can even be accessed, so, once into the desktop, you don't have to deal with decryption.
If you really want to protect your filesystem against read access, you should consider whole-disk encryption -- but you'll have to move the boot loader files to a non-encrypted partition before you do this.
