G'day there ...

Yes the 120Y tops will raise your car a fair bit.

It is not hard from (10 yr old) memory to swap the strut tops (and bearing and spring tops. may want to consider which springs to use).

I also think there are some variations with the steering arms (under the struts)

I'd be using the ones that came with the struts.

With the mastercyl, no real prob (unless it has as a booster - why would you???)

Brake lines - you could start with the 120Y ones, but prob easiler to start from scratch.

I could help with the brake lines and I'm chasing up a new bmc for someone else at present.
