OK.
Porter Cable, DeWalt, Bosch, Makita, Hitachi and Milwaukee all make excellent routers. Triton out of Australia is also an excellent router.
For a serious woodworker you should be looking in the 2HP plus class so you can drive some serious bits and expect good service life.
half inch bit shanks are less subject to deflection under stress and build up heat much less quickly so the bit lasts longer, resin build up is less and burnt wood is reduced.
Variable speed is a desireable feature since it can reduce kickback, wood burning, tear out etc. So is a soft start motor.
For a fixed base router I strongly prefer d-handles as they provide much more positive control and greater switch safety. Many router's offer d-handle bases as an accessory.
I have two routers personally, a Porter Cable 690 with both fixed and plunge bases. It is a nice basic 1.5 horse router with collets for either .25 or .5 inch bit shafts. It's noisy as all get out and is only one speed, but it's a workhorse light-duty router. My table router is a Bosch 2.5 horse fixed base. It's a little under-powered for panel raising bits in less than 3 passes, but it's a good, rugged machine.
My dad's shop contains three routers. A d-handled 2.5 horse Bosch, a 2.5 horse Bosch plunge router and a big 3.25 horse Porter Cable fixed base router in a JessEm/Jointech Mast-R-Lift base. This is a frighteningly expensive set up (about 250 for the lift and another 300 for the router motor), but makes repeatability possible and provides exceptional control and ease of adjustment and bit changes from above the table top. Along with the Bench Dog and Woodpecker professional systems, you are talking about the best router table systems short of a CNC mill.
There are a number of router table router alternatives though including the Router Raizer (an aftermarket add on for many brands of plunge routers that allows adjustment from above the table) The Triton router is set up for adjustment from above or below, so is the latest Milwaukee Plunger. Many of the router manufacturers are building those features right in.
Router tables: Depends upon what you want to do, how much space you've got, etc. My dad's router table is part of his Tablesaw right hand extension table, and they use a common fence, the Jointech SawTrain fence system. The system is set up for making complex joints on the router table side, mostly for smaller casework, boxes, etc. I like this system for that purpose. The Incra system is probably as good.
The Leigh router jigs are more versatile however, though most people who use them professionally have more than one to limit their need to be constantly readjusting the things.
The heavier the router going into the router table, the tougher the table itself must be. A set up like my dad's will cause many router tables to sag and need reinforcement around the router plate insert to prevent this. Most of the portable router tables are fairly light duty and I wouldn't recommend any of them unless space is at a premium. The Rousseau and Bosch units (the same company makes them) are pretty strudy though.
Router bits: Carbide is king. But all carbide isn't equal. For bits that are going to be getting a regular work out, you may want to spring for premium grade stuff like CMT or Freud. The Taiwanese import carbides (in the big sets for 125 bucks or so) are getting better. Most of my bits are imports out of the Woodworker's Warehouse brand. They cut pretty good, not perfect, but pretty good.
Some accessories to consider: Router bit cleaner and lubricants to remove pitch and resin build ups and keep the bearings spinning freely, as well as to prevent corrosion. are a good investment. Dust collection set ups to reduce the dust you'll be breathing when working are also a must have. My dad's shop has a 1200 CFM dust collector and a good Delta air cleaner for the finer dust. These make working in the shop a much nicer experience and dramatically reduce the fire hazards.
hope this helps, out of time now.
