If you're up to a trip to Dallas, there are a couple of fish stores that have a reasonable selection of plants that you can keep in a 'low light' tank. As patryuji stated, the 'grass-like' or ground-cover type plants like Glossostigma require relatively high light.
Most Cryptocoryne species and all Anubias species will do well in lower light. There are enough variations in those two genera that you can have tall, strap-like plants in the background, accent plants in mid-ground and low-growing plants in the foreground (or whatever other combination you might desire).
The Fish Gallery on Greenville Avenue (slightly north of the intersection with Park Lane) has a number of nice Anubias species available, along with a few Cryptocoryne species. Boutique Pets on Garland Avenue near the intersection with Buckner Boulevard has a number of different Cryptocoryne species and some very nice Anubias that just came in a couple of days ago. Check these stores out if you have the chance!
Of course...you can always spring for the extra cash and buy a light upgrade for your new 75gallon. You want to shoot for about 2.5 watts per gallon (translates into about 190 watts of light) or more if you want to keep some of the 'higher light' plants. At that level you could try things like sword plants, Vallisneria, and many others.
