Yep, Ive finally gotton round to using it. So I decided to start with baby steps. Took a sniper rifle mod I downloaded, changed name, ID etc. and some of the stats. Then added into the Megaton player home. Went into the game, and my weapon wasnt there.
Looks like Im gonna' be a slow walker.
:(
I would suggest learning off official sources, rather than other mods. Although, learning from other mods is neccessary, it is not always the best idea when you've no experience with a new language, or platform.
Go to http://geck.gamesas.com/index.php/Main_Page, and check out the http://geck.gamesas.com/index.php/gamesas_Tutorial_Layout. From here, you can learn almost everything you need to know. You will also need a http://fose.silverlock.org/Fallout3Commands.html if you plan to do any scripting. If you GECK search of those commands, you will usually get an in depth explaination.
Then, in due time, when you are ready to move on, http://fose.silverlock.org/fose_command_doc.html commands will help you extend your modding abilities even further.
Good luck,
