Run for fun.

I bought some of those $8 Asics ones (at Running Warehouse) for biking to work in the morning. So far, for $8, they've been great.
Running is dumb.
I bought some nice Pearl Izumi ones. I used them for 5 minutes pre-race, put them in my drop bag, and forgot to pick up my drop bag at the end of the race.
Don't leave them in a drop bag.

I have a pair of the poly/lycra arm panties. I love them and they seem enough for me in the winter...and it gets colder where I live. I get too warm easily...and I just push them down when I do.

I use my cycling arm warmers, generally together with a vest (that is what I used for Leadville).
The best cycling arm warmers have a loop at the top to help you pull them up and down on the fly.
Rapha and Ibex make merino blend versions, but they are spendy. Fleece lined ones are warm enough for running.
