Limiting memory is straight forward - look at the "ulimit" command 
in the bash manpage.

I don't think the Linux task scheduler can limit CPU usage to a 
percentage. "Nice" changes the priority of a program and allows 
other processes to run instead, and "ulimit" can restrict the 
total amount of CPU time.
