pls explain my server "ps"

hi,

i used the command ps, and it showed up quite few info. I am new to this, so could you help explain what it means, and if this status looks good? i have an Athlon xp 2400, 512MB ram

I've noticed that there were 87 processes but 85 sleeping - What indicates a process being sleeping?

The total memory is about 500MB but more than half of it was being used. I am not sure which of the 85 processes should be killed or should not be used at all pls explain my server

Is there any tutorial on how to do: SPRI - changes the priority of processes in accordance to level of importance?

Thanks for any input from you pls explain my server
