Hello, here's my comments:
1. don't see a CPU cooler, since you're getting a k CPU I'm assuming you're going to OC, at which point you'll need something better than stock.
2. get 2x4gb ram, it will only be ~$10 more.
Buy your motherboard from Microcenter as well. They are still offering $50 off Z68/Z77 Motherboards with any "K" series chip like the 2500K or 3570K, but that price (processor and Motherboard) are only for walk in. The price is not available for online sales.
While you are there, buy this 8GB (2x4GB) 1600 Crucial Ballastix ram for 39.99
