Most of the suggestions here are very good. I would like to suggest a couple of others.
At least once a week, depending on usage, disconnect power from the computer. This is especially true for the newer machines. When you press the power button on the newer machines, it does not actually disconnect power. The machine may still supply power to the memory chips. SO, they never get cleared.
Also, there is a program called Cacheman which will recover unused memory.
I hope this helps.

"Also, there is a program called Cacheman which will recover unused memory"

Is this shareware or off the shelf?
