The motherboard and CPU don't match. You need a socket 1366 board for the i7-930. Those boards are fairly expensive, so you could always drop the CPU to an i5-760 and keep the board you've listed.
Memory wise, the socket 1366 boards support triple channel RAM so if you go with that you might as well get a 3x2GB kit. Otherwise, a 2x2GB kit will be fine. Get something with a heatsink so they don't hold you back when overclocking.
Speaking of overclocking, while you're upgrading you should throw in a cooler. The Hyper 212+ gets recommended fairly constantly in this thread:
