This is one of the best programs to use for quicktime movies. Also, if you get a high-end 3D program such as Maya, you may also wanto to have After Effects to put the frames together.

Photoshop. What else is there to say? Ya got to have Photoshop.
As far as computer programs go, this should give you the best of the basics for around $1600 USD.
Also, you may wish to get a good mac, a dual 867 with 1 gig of ram should do just fine.
With these three things, plus a little of your own personal favorite programs and tools, you can get a very good machine set up to produce a coldstone game for about $3500 USD plus whatever you would want to spend on a 3D program if you use one. If your budget is substantially higher than this, I would reccomend that you spend the remainder on people to do stuff for you (artwork, audio)
Naturally, if you're going to use a 3D program for your graphics, you should just use whatever you know best. Also in 3D, ram is more important than processor power. Since this is for a coldstone game, I doubt you would ever need to know what a render farm is, but if you plan on making a LOT of 3D or movie stuff, you may wish to get several computers and several licences of the programs you use, so you could divide the rendering time between several computers.
