Specialized body geometry saddles always treat me right. The stock saddle on my Sirrus is mighty comfortable and I dont feel it after a mile or two, and I have yet to wear my cycling shorts with that.
As far as shorts,
www.aerotechdesigns.com and their men's pro bike shorts are a great company and great shorts. I bought a pair a bit over a year ago, and they are very nice, MADE IN THE USA and made very well, at that. You can spend more on a Taiwanese or Chinese product and not get the quality of the aerotech shorts. They have a few different models to chose from, the pro is the low end of the line, but still very good. the main differences are panel number and chamois quality. I don't know of many other US cycling shorts manufacturers...
