The Rock Chucker is a great press, and that price is not too bad.
Some suggestions:
Hand primer: Lee Auto Prime with shell holders, or RCBS Universal (doesn't need separate shell holders)
Dies: 45 ACP - someone's Carbide set
308 - anyone's standard 2 die set
You'll also need shell holders for each. If you get the more expensive Lee sets, you'll get the shell holder in the sets.
Tumbler: lots of choices. Mine is a Lyman 1200 that works just fine. Corn cob cleans best, while walnut shells give a great polish. Use Flitz or something with the media.
Case lube: Imperial sizing wax
You may also consider a media separator such as the small Dillon model, loading blocks (the universal ones are handy), and MTM or other boxes for your loaded ammo, a case trimmer (you probably will never have to trim the 45 cases), and a source for brass. Depending on how hot you load the 308, your cases will last from 3-4 shots up to a dozen or more with annealing.
Edit: reread your post - get the trimmer too.
PS: also read the Sticky about new reloaders and equipment. Particularly books.
