Help me!!!! How do I mod?

[Your Ma]

HELLO PPL!

Ive got a ton of ideas that i would like to make mods out of, these are:

1.) A huge, open air map, where i could use most of my mods
2.) A turret for humans to operate which consists of 2 rifles with regenerating ammo
3.) A turret that can be operated by aliens up to and including basilisk, that shoots adv goon spikes at double speed of adv goon, 30 or so spikes held at any time, regenerate at x1.5 rate.
4.) Vehicles for humans (truck/tank sort of thing transporter with gun mounts for humans inside, it ould be rather slow moving)
5.) "Vehicles" for aliens (large alien secretes acid with spike mounts for garrisoned aliens, slow moving again)
6.) A third race, machines, twisted human creations. Like steam-powered sort of, bio-mechanical monsters, will explain more, buildings slowly regenerate helth.
7.) A flying alien, fastish flying, human speed running, claws
8.) Spiked disk gun, sends out ninja stars at slowish rate, does good damage.

Those are all the mods I can think of, I dont want ppl saying, well that sucks, I want constructive critisism or advice.

But mainly in this post I need help on how to mod Tremelous and Make maps for it.
Things that would help are

Programs or files that would help me (graphic designing, map making, source codes)
Guides or info on how to use all above (V.IMPORTANT)
Support

Thank you ppl, I really do need help, I halfish understand source codes, but need info on what means what, and what to do after Ive modded (how to install, publish, create a file for, etc.)

THX PPL!

What operating system are you on? If windows, and you're serious, my advice would be to get some kind of linux, for two reasons:
1) most people here are linux users I think
2) from what I've heard compiling and so forth is easy on linux (well, easier)
If mac or linux, the first step is probably to get a subversion client and type in a command line:
svn co -r 872 svn://svn.icculus.org/tremulous/trunk tremulous
this will get you revision 872 of the source code, which last I checked was the most recent version. Then do what you like. Then, if you're like me, whine to IRC about how you can't work out compiling (thanks to them I now can, best place to get help really)

In case your OS is MS-Windows there is no problem.
You can use TortoiseSVN for getting the source code from repository :
http://www.tortoisesvn.net/

You can use Visual Studio C++ 2005, express edition is free :
http://msdn.microsoft.com/vstudio/express/

You can get the project files from this project (by r1ch) :
http://svn.quakedev.net/viewcvs.cgi/trem/trunk/

And like Caveman said, search for "quake3 modding tutorials" like this site :
http://code3arena.planetquake.gamespy.com/

You can also search this forum, there are some other threads related to this subject.
