do a search for the "best" low lights plants, there are a few threads just recently in the "Low Tech" section of this forum, read thru there, that's where I got all the info for the new low tech tank (29g in my sig) I'm setting up, I think most of your general questions will be answered by rooting around in the low-tech forum...
I would "GUESS" that 2wpg is the max you'd want for a low-light setup, remember its a balance between Light&ferts&fishload&plantload&CO2....low CO2 means lower lights...
I think lots of low-tech guys still do Excel, I'm going to, and I'll still be dosing dry ferts, but like a SMALL % of the recommended dosage, my .02
