I do not know of any good websites right now, but I can give you a few hints on how to start.
-Make sure you know director before you try to program Lingo, or it will be hard to do.
-Start basic, don't try to program a game (I don't know if thats what your shooting for), instead, program somethign simple like a website
-Make good use of this forum. If you post what you want to do, others like myself can tell you how to do it. Personally I've even made people director movies to help them.
-The lingo dictionary in Director is fantastic. It doesnt show you how to make anything, but if your looking for a command its great.
There are a few books i've seen out there, but i never touched a book and am programming web game engines with their own map editors. The key is to pool your sources and be patient, it took me 3 years to get to this point, just using this forum, the lingo dictionary, and a few of the sample movies that came with director.
Happy coding. If you need me to send you a simple lingo example or two i'd be happy to, just to start you off. Thats got to be the easiest way, just to look at other people's code (as long as its heavily commented).
