Help with VPIP for SSNL, Please!

Thanks for the time fellas. Let me ask, I've returned to playing small stakes no limit about two weeks ago and wanted some advice. I have a VPIP of 17 percent right now. I'm at the 10 and 20 dollar buy ins.
1. Is that a good number?
2. Is there a recommended preflop raise figure for NL at the small stakes?
3. Agression, is my 1.7 too weak?
Thanks for the time. I appreciate it. I'll buy Ed's book in May when it comes out.
