You can't beat the RCBS "Rock Chucker Kit", it has all the basic components (except dies) You will need to purchase some needed extras (calipers, case lube, etc) Here is a link to look at:

Now, that will cover the rifle question, excluding the .22.
You will need totally different equipment for the 12 ga.
I would safely guess you could be into the 450-500 dollar range to get set up, maybe cheaper if you shop around some.
The initial expense is the hardest, or was until the price of powder and bullets hit the roof. Pick a round you like the best out of the bunch, get set up and start stock piling as you see it on sale.
