Totally agree with Marc. Learn to use what you already got.
Get a DV camera, any DV camera, and learn the shooting techniques. Angles, composition, lighting, manipulating focus, WB etc.
Get a fast computer (yes, the $ 3000 PC is a good idea anyway because you can use it for absolutely anything), stay with Adobe PE or try something like Avid FreeDV just for the sake of learning and... and I don't know, maybe get a cheap tripod, lights, batteries, whatever. Just keep practising. Do short films. Shoot events for friends, family and even profit.
Think again of a career in 5 years time.
Best of luck!
