A yagi is too narrow. A sector would be the prefered antenna. An RF amp is probably unneeded, and certainly 1W is too much. A repeater may or may not be needed (probably not), but there is no way to tell without a site survey.

Bottom line: You need to properly design this. It can be done, but just from the questions you asked you need to learn some RF engineering basics and to learn about running a Wireless ISP. If doing the math is too much for you, then hire someone to do the design.

You will also need to learn proper networking. If you only experience is with NAT on a home router, you need to hit the books. Again, if this is too much you may need to hire an expert at least for the initial design is done, and you are up to speed on the finer points of how networks run.

Also, come up with a solid business plan. This IS a business, and your about to start playing with the big boys. The $500/month figure usually reflects a multi-year contract for a T1, which effectively will lock you into a $12,000 to $18,000 commitment over 2 or three years. (T1s are not cheap to install. No provider will let you just try it for one month.)

Search Google for "WISP" and "Wireless ISP".
