Hardware upgrades on 12 year old stationary PC

CPU Central Processing Unit. GPU (Graphics Processor Unit), yes, thats your graphics card. if you really only play lfs, not much need to upgrade that too. but as swift and i did, a decent old GTX 560 / 580 or above is rather cheap and a good upgrade to your current card.

One thing we totally forgot is your operating system. To be able to use more than 4GB ram you need 64bit Windows.

Im not too sure if it makes sense to go for more than 8GB ram and i think the prices are way higher for the 4GB sticks.
