Looks Like you have plenty of Room for expansion!!! Use 20Amp Circuits rather than 15Amp Circuits. That way you can run more equiptment with less wiring cost. If you need further assistance feel free to contact me and I'll walk you through it!

thanks a lot!

should i use solo 20 amp or can i use a dual 20 amp breaker?

should i use 12 gauge wire?

again thanks a bunch for your help and any future help i might need.
