Welcome to the forums.
A good way to get up to speed with the steps of making a film is to get Timothy Albee's book, CGI Filmmaking: The Creation of Ghost Warrior, available from Amazon, and probably all good book stores. You can find it at Amazon here -

It is excellent, and goes through all the steps of making an animated short, from pre pre-production to distribution.
Also, if you need help with modelling and creating scenes, SimplyLightwave is the best place to be! There are plenty of free tutorials to have a go at, and the others (that you need to buy) are also excellent.
If you have any more questions, feel free to ask.
