grep -l 'iwantthisstring' {list of files} | xargs grep -l -v 'idontwantthis'

The first grep finds all the files with 'iwantthisstring'.
The list of files from this grep is fed into xargs which
runs grep -v on those files listing the ones that do NOT
have the string 'idontwantthis'.

As I've said a number of times before, 'xargs(1)' is your friend!  :-)

There's yer homework...
