You expect us to recommend anything other than wool? 
Right now you definitely want arm and knee/leg warmers - this is the time of year in Ohio when we start out on a ride at 45°F and it'll be 80 by afternoon. Those little tubes give your knees some thermal protection and keep your core from getting totally chilled when you're starting out, but they're small enough to push down around your wrists and ankles, or stow in a jersey pocket, when it warms up. On your knees, IMO wind protection is the main concern, so synthetics are probably better than unreinforced wool.
In a couple-three weeks you're going to want full-fingered gloves. If you don't plan to ride past Thanksgiving, chances are you won't need heavy gloves. Light ones that just give your fingers some wind protection are good to days with a high of 50-55°, for me.
A light wool base layer is a great thing to have, too. Oooh look, SW sleeveless base layers are half price, every size but mine.
Those particular ones are great for fall days because they're very light - again, they give your core some warmth starting out, but aren't so heavy that you overheat when it warms up. A long sleeved base layer will be good when it gets a little cooler. A zippered neck gives you another ventilation option as the days warm up - but then, you may have some discomfort from the zipper, so it's really personal preference. Buy your base layers to fit close but not compression-tight against your skin.
You may want a wool bra if you get clammy b**bs. That's not an issue for me - mine stay warm as long as I have something warm on over them, even though my sports bras are inevitably soaked - but some women have that problem. They're really comfy, but not cheap.
