So I appreciate all the information. Here's some more data.
RDRL is a Shiamano 105
FDRL is a Shiamano SM-AD11, that's all the markings I could find
Crank is a Shiamano RX100
I feel my current gearing is too closely spaced and I frequently skip multiple gears. I also find that there is too much overlap (i.e. small crank gear with small cassette gear is higher than large crank gear, large cassette gear.
Based on advice here, I've ordered a Shiamano Claris FC-R2000 crankset (50/34). I've made an appointment at the local bike coop to help me install it with a new chain. We'll evaluate the cassette at that time.
To provide more info on the riding conditions here. I'm in SE Pennsylvania in Avondale. We have what folks like to call "rolling hills". I can handle most of the terrain currently but where I struggle are the rather steep hills that are longer. I see others doing those on the small ring of a triple. I've tried that and it is sooo much easier for me.
