Zune, you are not alone.
The three major forum sites are this one, Amibay's AmiOracle, and the French "English Amiga Board." All will help you problem shoot and Amibay does a lot of hardware trading.
Desiv is correct about your problem. In addition, Amigakit sells an Amiga 23-pin video cable to SCART tv input and a few US tv's (Samsung & Sony) have them here. If you only want to play games, then you don't need a scan doubler; if you plan on text work or productivity projects, then they are extremely helpful. The best is the Indivision ECS @ $107 USD, but a GBS-8220 will only run $30 to $50 vs that. The A500 was popular in the US while the A1200 was popular in Europe; as luck would have it, the A1200 was more advanced and easier to upgrade and enhance. The better US choice were the A4000 and A4000T.
Now back to WinUAE. There is a guide to make a PC act just like an Amiga with booting directly into WinUAE, but under the hood is DOS with a sandwich of WinXP. Some folks use this as their Fait Accompli Amiga because you use standard hardware and get good speed running Amiga programs. I myself grew up on the old hardware (punch cards and teletype terminals) and about crapped on myself when I saw the chance to get my hands on my own computer. So I run Amiga software on Amiga hardware (another topic), others like the Amiga OS as a puzzle to be solved -- it has that "tweak me until my nipples hurt" feel to it.
But before you start getting lost in that dream, check you wallet and get a pre-nup. It may be a "no go" situation.
