I'm in a bit of a quandary. I've currently got a D7000 and an 18-105 lens.
Ive recently (this year) switched back to SLR's after a decade of using
digital point and shoot. I'm certainly pleased with D7000, but am finding
the 18-105 to be a bit too slow in low light (indoors without flash) and am
thinking of buying a faster lens.

increase the iso or buy a faster lens. the former is a *lot* less
expensive (as in free) than the latter, so try that first.

Also I've found some of the (cropped) images to be not quite as sharp as I
would like. This mainly seems to occur in low light shots.

are they handheld? if so, that's probably camera shake. get a tripod or
monopod, or increase the iso so you can use a faster shutter speed.

another possibility is that you aren't post-processing them properly.

I'm also keen to try some macro photography too, and have been thinking
about a macro lens, perhaps extension tubes or even a bellows.

many options there.

My quandary is this. I'm not (at all) sure that I'm satisfied with a DX
format and really don't want to buy new lenses and accessories and then
find myself needing to re-buy them if/when I buy an FX body.

nothing you've said so far suggests an fx camera would solve your
problems.

also keep in mind you can buy fx lenses now in case you think you might
change to fx at some point in the future.

if you do switch to fx, your 18-105 would need to be replaced since
it's a dx lens, but it isn't an expensive lens so it doesn't matter
that much, and it would actually work on an fx camera, but with the fx
camera in crop mode.

So, what do you think. Should I spend more time and practise getting the
best out of my D7000 or switch to an FX body now? Cost is not particular
issue - that said I don't want to be wasteful.

spend more time learning the d7000.
