Is there anyway to get another basic lens other than the one in the Hutts storage room? See because I can't get it now that I took the quest of the man who wants a female dancer.

I don't think there is any one place to get a lens. ( I assume this is the one to build your lightsaber? ) I got mine on Dantooine, but I think you can get it anywhere. More than the specific location, certain quests give out rewards. If you don't have a lightsaber yet, the reward will be a component; if you do, the reward can be a whole lightsaber, or something else. This is what I'm guessing, based on my experiences. I haven't played Nar Shaddaa as the first (or second) planet, so I'm not sure which quests would give Lightsaber components.

i got all my parts by going to Dantooine,

saving Jorran (sp? the salvager in the Jedi Enclave) and buying his jedi relics ($1000), and then having an alignment that dipped strongly towards the darkside (works for lightsiders too) to get Visas after me

-- I then had all 3 components for my lightsaber.
