Definitely filter it through a coffee filter as well as the t-shirt. You don't want to be building up sediment on the inside of the stopcock.

Unfortunately not. In order to be properly soluble in water, you need to make a salt of the DMT (i.e. do an acidified extraction). Also, due to partition coefficients, you generally can't get 100% of a chemical with a single extraction.
A seperatory funnel isn't really helpful for pulling DMT with a straight-to-base extraction. It is useful in doing a sodium carbonate wash of the nonpolar solvent once you've extracted.
But if you want to use the seperatory funnel throughout, you'll have to go the acid/base route. Marsofold's is very consistent, and Coschi's looks good as well.
