Good advice from Ritten and Barney as usual. Keep the rifle short and fairly light. 22" barrel max will do anything you want to do. 7/08, 308, 270, 280, 30-06 will cover any and all hunting needs you'll ever have. Forget knockdown power, put a quality bullet in the right spot and animals die. Assuming you're not a reloader the 308 is king when it comes to factory ammo available. If it was me I'd be shopping for a clean used Remington 700 in one of the sporter models (SPS, XCR, BDL, etc). Then a quality scope in the $300 - $400 range. Leuopold is my favorite but nothing wrong with Nikon and others. I'd stay in the 3 - 9 x40 size range. Dont stress about free floating from the factory, thats easy to change later if it doesn't shoot. Lots of Remingtons have a pressure point at the end of the barrel and shoot great from the factory. Tikka T3 Lite's have a great reputation for out of the box accuracy also.
