Yes. You can use your main account's email to recruit yourself.

You can do either, however a gamecard is instant while a credit card isn't charged until any free time that comes with a copy of WoW expires. If you want your RAF pets sooner, use the gamecard.

It takes 7 days from the time you activate, upgrade and add time to your RAF account, to receive the pet(s).
I wrote up a blog post/guide
on my experience RAF'ing myself if you'd like more details on the process.
