Using a golf ball or wood ball is good for speed stick handling. Ideally, though, try and using something still about the same weight as a puck. Smart Hockey makes good weighted ball options.
For shooting, I only recommend people use pucks. Preferably ice hockey pucks but if you want to use other options such as Green Biscuits make sure its the same weight as a puck.
