The monitor cable might be a problem, depending on the quality and of the
DB-9 extension cable. I have seen poorly grounded monitor cables give
the screen the jumpies whenever the internal disk was accessed, so watch
for that symptom and if it appears, try another extension. I built a 25 ft.
extension once, out of a DB-9 and 4 lengths of standard cable-TV coax,
but that's probably overkill for anything much shorter.

The telephone cable has to be of the 'handset' variety, or it will be the
wrong size. For the keyboard, the thing to watch out for is resistance in
the cable. Just a little too much, and it won't work. You can buy one off
the shelf, and it will work, while the one next to it won't. See if you
can convince the store to let you bring it back and swap it for others
as many times as it takes. There seems to be no rhyme or reason to finding
one that's good.

There used to be an ad in Amazing Computing for DB-23 connectors, or if
you really get stuck and really would rather have the right thing, a local
dealer usually stocks them (Vancouver BC. (604) 873-2174, ask for Ken or
Duane).
