Hi, 
looks like you need to surround the {print $3 ","  $4} with ' (single
quotes), like this:
'{print $3, "," $4)'

as for help,
try "Sed and Awk" by O'Reilly Assoc., it's a very good book on the
subject, and at the mean time, try man awk :P
I know it's tedious read, but it's actually pretty comprehensive.
