Install Autokiller from the market and preset it at Extreme or Ultimate. Depending in which setting, you will have good amount of RAM available.

NO, do not install a task killer. Android works differently. Basically, it uses up most available memory and calls upon it when needed. It will free up memory as it needs to.
Blackberry works differently and the available memory really makes a HUGE difference.
My phone is VERY fast and I an constantly at 30-50mb free.
I said AUTOKILLER, not task killer. They are not same.
