As expected, Taylor will get 2 awards, Country Album and country duo, Goldderby users also think the same.
For country song, Begin Again was a long time ago for Grammy voters, and it didn't make a big impact, really.
AOTY is a mission impossible for Taylor for the next 15 years ,if you look at the history of the Grammys. AOTY is the biggest award and they don't give it to someone a 2nd win just because she has the best album of the year, Taylor can win in the future, but only if she becomes a respected veteran (like U2) This year, probably Daft Punk will win.
I still think Taylor can perform with Ed Sheeran, if not, she'll perform solo unfortunaltely. Her performance won't be the biggest performance of the night, because there are some other performances that GP anticipates (Daft Punk + Stevie Wonder, The Beatles, Madonna's surprise collab)
And i think collaboration with Lorde in LP5 is very likely. Lorde continues to praise Taylor, this means something
