This is one option.

Yes.

because you can say:
let x = y
z = q
w = l
in ...
so it needs to know where the boundaries between declarations are, hence
the need for semicolons. therefore, if you have embedded lets, you need
braces to delimit them:
let x = let y = z
q = r
in l
in q
would be ambiguous without layout/braces&semis.

p.s., I'm surprised you're having difficulty with tabs; a few people have
had such problems, but usually there's an easy fix in the editor. I don't
really know enough about this to say one way or another thogh...
