You should see if you can buy the stock through your 401(k). Sometimes there are a few individual stocks you can buy through your 401(k) but it's usually limited to mutual funds or common stock of your own company.
I would look into setting up an etrade account. I have one. You don't need any special license or permit to buy stock. All brokerages have fees associated with trades. You're not going to get out of paying a fee for buying stock.
You will receive a tax form by January 31 of your gains or losses for the previous year. You have to pay capital gains on the appreciation of the investment. You can deduct any losses.
The upshot is you can do it yourself through etrade or sharebuilder, and they'll let you know next January what you can deduct or claim as income on your taxes.
It's not very complicated. Don't be intimidated by it. Normally, I would recommend you go through an advisor, but since you are interested in buying one particular stock, you should be fine just doing it on your own.
Good luck!
