To get the number of threads for a given pid:
Where nlwp stands for Number of Light Weight Processes (threads). Thus ps aliases nlwp to thcount, which means that
does also work.
Percent of cpu usage per thread you can get with ps command:
The way it is calculated is described in ps manpage:
Currently, it is the CPU time used divided by the time the process has been running (cputime/realtime ratio), expressed as a percentage.
Memory is not allocated to threads, and often shared across threads. This makes it generally impossible to find the memory usage per thread.
