Alright mate, welcome to the forum
Congrats on passing your test. What age are you, hows the insurance quote going.
Advice as above. Wrap up warm with layers of clothing and gloves. I dont do much winter biking these days but my 18yr old son uses his bike all year round. He has thermal inners, gloves and mitts type outers and says that seems to work. Try and hose your bike down at the earliest opportunity (although not if its going to be icy, or you'll have a skating rink to negotiate)
Also treat all car drivers as if they havent seen you and be prepared.
I have advised my boy to do a (mental) running commentary of the road ahead similar to that required on a Police driving course. Try that, it will make you more observant to whats happening around you.
Good luck and safe riding
