I hate to burst your bubble, but all that and an automatic really don't mix.
On top of that, what you're talking about isn't as "simple" as you make it sound, it's really quite a challenge to do correctly. If you had bought an automatic to perform these mods on I'm not so sure you are in the right place to even try to do any of it.
Of course, you could always swap the transmission, but that would just be more cash poured in... sry bud, I just don't see it
