I am currently using 2GB of pc6400 Ram @800 Mhz for Windows Vista. I was planning on upgrading to 4GB. I was wondering, do I need to use Ram from the same company or can I mix it up. Also, how much faster would Vista 64bit be with 4 GB instead of just 2?

That depends on what you will be doing with the computer. If you use memory intensive programs, such as video or image editing software, then they will benefit from the upgrade. Also, some newer games will benefit slightly from the upgrade, but most will not. However, with the price of DDR2 RAM these days, it would still be a good purchase in any case since 4GB will come much more desirable in the near future.

Do I need to purchase the RAM from the same company?

Generally, no. Most computers now use paired memory, i.e. sticks 1 and 2 work hand in hand, and sticks 3 and 4 work hand in hand. So 1 and 2 should be the same manufacturer (and the same model, and the same speed, etc), while 3 and 4 should be the same manufacturer (and the same model, and the same speed, etc). But 1/2 and 3/4 can be from different manufacturers.

Does that make sense? Maybe I rambled... basically the two sticks of RAM you're getting have to be the same as each other, but they can be different from the two you already have.
