I'm 71. I'd recommend any decent brand of padded cycling shorts or bibs (nashbar.com, performancebike.com, etc), minus any underwear.
I've been riding on saddles with a center cutout since about 2003.
Both of my bikes have a Selle Anatomica X series. Love them.

Gradually build up your mileage--sitting on a bike is not a very natural position and it takes time to adapt. And lots depends on what kind of bike you have too.
