i am like you but ive been running now for about 4 years (20years old), tried speed sessions during hs track (4:28 mile pr) but hated it. i usually run three times a week 10miles each, always at night. I found that running 30-50 F is the best for any type run, however i prefer it to be sub zero, i do wear underarmour tights and mockneck. before i splurged on them i wore a long sleeve cotton tee with a sweat shirt over it/ i wore knee high socks, running shorts and sweat pants over all that (remember this is in sub zero with wind, i live in chicago). this along with gloves and a head band always kept me warm, if you have anything like sweatshirt material or fleece they keep you warm but only when there isnt wind. also, in my case i sweat when i wore them, that was the primary reason for the underarmour. as far as your concerned, you have the right clothing as long as it keeps you warm and comfirtable.
a little recomendation is to go to an outlet store like jcpenny, khols, value city, or any other store that has regular sales and only really sells clothing. they usually have brands like c9, athletec, and others that are athletic clothing, a pure polyester long sleeve tee under your sweats will wick away sweat and keep the wind bite away ( usually 5-15$) just always remember to wear GLOVES GLOVES AND MORE GLOVES.
