Answer 1

This information can be found in the manual of ps(1):

C        processor utilization. Currently, this is the integer value of the percent usage over the lifetime of the process. (see %cpu)

Answer 2

They should be the process flags. From this page (the ps man page):

The sum of these values is displayed in the "F" column, which is provided by
the flags output specifier.
1    forked but didn't exec
4    used super-user privileges

zero, I guess, would be a normal process.
