The CoolerMaster PSU he recommended will be plenty of power for your system.
After you get all of that done, you may want to look into getting a full-fledged CPU. The Sempron you have is basically a gutted version (with 1/4 the onboard cache). You can get an OEM Athlon 3400+ Newcastle for $147, or $156 with different stepping.
