Thank you so much in advance!

Perhaps I should take a bit more time laying out my memories precisely before answering lest I be accused of making something up.
There is – or at least once was – a station, like Oslo, actually inside the Trondheim airport [Vaernes Station] and this station has [or at least once had] express service to the city center running on the hour IIRC.
I am afraid that I cannot comment personally on where best to catch the train to Storlien but a quick glance at the NSB website shows day trains to Storlien directly from Trondhiem Sentralstasjon [Central Station].
As for English, my experience is that a significant percentage of the Norwegian population speaks English – and I mean accent free, idiomatic English, though it did seem like there were progressively fewer English speakers the further North and the more rural one went.
Oh, and Trondheim is a beautiful city – but I suppose you already know that.
Cheers and have fun.
