Your recip table right there looks like a good number to me.
Personally -- for someone new to submitting -- I'd recommend submitting to around like 30 LL's from different folders and then you can narrow it down from there the ones that don't seem to be accepting you or giving you good/decent traffic.
Or if you're a die-hard you can add more from there. But at least that would give you a good sample of what link-sites will be doing for you. Good luck!
