I live about 100 miles inland without a bubble sight or artificial horizon, so I have looked to lunars for sextant practice. If I use my GMT and lat/long as a given, would I still need the altitude of the moon and another body or just the lunar distance between the moon and the body? That way I could calculate a time and compare it to GMT.
Alternatively perhaps someone could suggest another way to practice without a horizon.

No you do not need to observe the altitudes of the two bodies. You can 'pre-compute' them by using your Lunar sight time and your assumed position using any of a number of methods (ie calculator, computer, even the program available here on the Starpath website. The modified Stark Lunar Form available on the Starpath website will lead you through the clearing using the Stark Tables. There are directions to follow step-by-step.
There is also a blog entry on the Starpath website for doing Lunars with the Stark Tables.
