Some great info on here, figure I'll throw in my .02
Ditto on the 1 piece cleaning rods. I use Dewey rods at home and Boresnakes at the range.
You can't go wrong with the 700.
I generally plan on spending about 2x the cost of the rifle on optics.
The cost for .223 has risen quite a bit recently. The cost of lead and brass has also risen dramatically, but I think .223 has slightly outpaced even the cost in materials.
7mm-08 and 6.8SPC are both excellent calibers that offer low recoil and good down range performance. For me these are the minimum calibers for deer size game, but wouldn't be total overkill on varmits. If you decide to take to the field at a later date.
22LR and 17HMR are both good choices for plinkers, you'll learn to shoot every bit as well using these as larger calibers.
My Savage 116 in 7mm WSM wears a Leupold VariX III 3.5-10 x50 and has a custom muzzle brake. The recoil was reduced DRAMATICALLY, but the noise level rose in kind. I double up ear pro, but I do get a lot of strange looks at the range. In the field I have never noticed the sound, but thankfully when combined with Winchester Ballistic Silvertips I have never fired it more than once when hunting. Knock on wood.
