There are a few things you should get before you start:
1) Get Nucelar Wessels guide to server setup. It helped me alot.
2) Get the Taldren ship modders guide. It explains the software and process for creating new models (ie: ships, stations, etc...). It comes with the plug-ins for Milkshape / 3d Studio Max.
3) Get the Engineering402.pdf guide. It helps you understand the DefaultCore.txt and DefaultLoadOut.txt files for changing ship specs and adding custom ships.
You should be able to get all of these from either SFCX.org, StarfleetCommand.net, or SFC3Files.com sites. Hope this helps.
