You can check if a directory exists using -e, and if it's a directory using -d. So you can probably just use the latter: 
    print "is directory" if -d "/foo/bar";

For your second question: 
    opendir DH, "/foo/bar" or die $!;
    my @subdirs = grep -d, readdir DH;
    closedir DH or die $!;

Sub-directories are in @subdirs.

Umm, embarrassing update: read chip's answer below for why my second answer is broken. So use his code.
