I haven't generally worried about the lower body for reasons mentioned above. I bought a Gill Adrenaline jacket that has worked ok so far. Wore it on the wet Seagull century this year. About 60deg and rainy.
For the feet I have some LG booties. They do a decent job if it is cold. If it is warmer I just wear my backup shoes and let them get wet.
I guess if it were colder I would want some pants. But honestly any colder (50's or below) AND rain, I am gonna do something else.
I also like the SK Raceblades. Quick on and off, and while not full fenders it keeps the front spray off your chin and the back spray off your back (and off the guy behind you).
