Yes, they share exactly the same notation.

No, but you don't have to adopt a harsh thresholding approach, and instead show the results in a gradation fashion.

The above specification assumes that there are 10 or more time points. With 7 time points, try

-mrr 's(Time,k=7)+s(Time,by=Group,k=7)+Age+Gender'

With this specification, you would be able to assess the association of each outcome with your outcome variable. However, I'm confused with your word "correcting": What do you mean by "correcting for them"?
