Well on just personal experiences whats the best thing to start at you know? Like the cheapest most needed thing changed (unfortunately) a Auto Rx8 2004 I would've like a manual but not my choice just glad to have gotten a car. I have read most of the forums and the biggest question i have really is where is the to start tuning up or (modifying) my Rx8.

Just to get you going.
this is what I did when I picked up my first 8 an 04 6spd

DOn't look for power steering fluid lol we dont have any ;-)
Oil and filer – 10W30 though mazda recommends 5W20 that's too thin
Trans oil change - Redline MT90
Rear end oil change - Redline 75x90
fuel injector cleaner - BG 44k
Change radiator fluid - Grab it from Mazda
Air filter -
Cabin Filter -
Spark plugs – NGK RE7CL and RE9BT (2 each)
Ignition Coils + Leads

These are all maintenance item, depending on how old your plugs and coils are you may or may not need to change them.

Get your CAT inspected for sure, if it's clogged it may kill your engine.
Your biggest issue right now is, 04 automatic it comes with 4 port renny.
Get the compression test.

Wish you all the best.
