I bought the books, read the web sites, watched the videos and ended up getting Marc Sommerfeld's router bits and one of his feather boards.
I made a whole kitchen using it and a whole bunch of individual cabinets.
I can't recommend it any higher for making the whole process really stupid easy.
As far as the tooling goes:
- Track saw for cutting the carcasses (optional - but - it sure makes the whole job quicker & easier)
- 3+ hp router in a table
- Sommerfeld bits & featherboard
- Kreg pocket hole jig
- Rockler Universal Drawer Slide Jig
Before making any decision - I suggest watching the Sommerfeld videos:
