Hi Swirly,
At it's very simplest, you could fashion a router table by bolting your router under a bench-top with the armature coming up through a hole. A length of wood as a fence held down by bolts in slots for adjustment would also suffice.
I can't help feeling however, that once started you will find more uses for your router table than you imagine, so I would start out with something a little better. I'm sure that you will be inundated with links to sites of plans for super duper router tables - mostly on the theme of Norm's on The New Yankee Workshop. These are great, but you normally need to have a router table in order to make them!
I'd start with a proprietry model such as the Trend Craftsman. You get a proper push-button switch, decent fence, dust extraction port, safety guard
mitre slot etc and if you want to upgrade to your own design table in the future you can use many of these componants.
As to routers, for table use you really need one with a half inch collet. You will also be able to use this for hand-held work although most people would keep it in the table and have a second quarter inch router for this.
Different brands have their fans - I use DeWalt, but in your shoes would look at a Triton.
