That Asus A88XM-A board should work well for you. A decent 500W PSU will be OK and a decent kit, 2x4GB or 2X8GB of 1600MHz memory will be good too. If you want to spend some more, you can go for 1866MHz memory but you probably don't need to. Any increase from the two speeds will be unnoticeable unless you run a benchmarking program which will probably show a slight increase.
I have used Team memory for several builds with 88X boards and have not been disappointed.\

Easy to set up in BIOS. Just enable XMP and the BIOS will set the timings and speed perfectly to 9-9-9-24 at 1600MHz.
Also an easy OC to 1866MHz if you want to go that route.
I don't know what is available for you, but look for memory with a CAS9 like in the specs above.
