Good choice, enjoy the upgrade. =) I don't think you'll have too hard of a time installing them, a lot of us got our start installing small things like memory or a new hard-drive and then caught the bug. =P
Just a few pointers:
- Make sure the computer is turned off. I also like to unplug the power cord.
- Ground yourself before handling the memory or the "innards" of your PC by touching the side of the PC case (assuming it is metal).
- Only handle the memory from the top or sides, never touch the metal "fingers".
- Line up the little notch of the memory with the little protrusion in the DIMM slot.
