Nothing wrong with the '30-06 (or the .308 for that matter). However, if you are going to start reloading you might want to look at the 6.5x55 Swedish. It's a great round with low recoil and it will do everything you need. It's very versatile and accurate.
For a good 3-9x40 scope there are lots of choices that won't put you in the poor house. Bushnell Elite 3200's, Burris FullField II's, Leupold VX I & II's etc - most if not all makers have a decent scope in that power range for a reasonable price. You have to do some comparison shopping and look through a few scopes to see what works for you.
