Use the symbolic form for permissions and use X, which is true if any of the 
execute bits is currently set, or if the argument is a directory.

chmod -R =r,u+w,+X .

(set read for all, add user write, add all execute bits if required) should 
give you 644 on files, 755 on directories and executables.
