Also, I just picked up a fairly inexpensive Suntour power shifter. I will try to find a cheap used shimano RD to go with it so if I can't stand friction shifting, I won't have spent too much money on it. I have never even used trigger shifters before, just very cheap twist shifters.
you out can use any derailleur with friction shifting. Just get matching chain with the cassette.
8 speed it best if you're only doing 4 to 8 miles a week. 8 speed parts are MUCH cheaper, and some argue that they are more durable as they use a thicker chain. IMHO a 10 speed chain is probably just as strong.
8 speed cassette is about $20, 8 speed chain KMC with quicklink is about 15. 8 speed derailleur is around $30-40 ( shimano Claris). The Shimmano Claris is good looking, light, and works flawlessly for the price. It can also shift up to 32t. I currently use it and never had problems, I commute 80 miles a week.
If you have narrow wide chain it's probably a 10 speed, 8 speed chain will fine since you'll be running it single up front.
