I don't know how many people here already know, but the Slavic and Eastern European Languages Resource Center has an excellent Georgian Reading Grammar available, in PDF format. It is weighs in around 35MB, so be careful on lesser connections.
They also have a plethora of resources available on Georgia in general: http://www.seelrc.org/webliography/georgian.ptml
There is also some Georgian links available at the UCLA Language Materials Project/Georgian
I hope some of you find this useful.
