I don't know the Trek 1000, but what you'll need to do is get a new wheelset with track hubs, cog, & lockring. That's pretty much it. The biggest issue will be the drop outs. without a derailer you will need some room to play with to get the chain tenstion right. If it has vertical drop outs, you can try to mess with half-links and things like that, but thats no sure thing.
You can probably keep your crankset depending on how its built. In order to resolve chainline issues you might need to have a couple choices as to which side of the spider you attach the chainring.
BUT, it seems like a decent roadbike and most people here, including myself, prefer a lugged steel bike over AL, so you might as well just hunt around for an old frame instead of destroying a road bike.
