I'm quite happily riding my bike with it's current drivetrain which is a 3x9 XT Octalink setup, most of which is 10 years+ old, on its 3rd frame and still going strong. Shifting at the rear is starting to get a little less than perfect and would probably benefit from a new mech.
I like upgrading stuff on my bike and could get a full SLX or XT groupset for around £200-£250 but I can't help thinking that a new 3x10 or 2x10 set up just won't offer me anything over my current set up (I like the 44x11 - 22x32 gear range that I have and wouldn't want a single ring set up). Should I save my money and just get a new 3x9 rear mech (XTs still available for about £45)?
Newer stuff is less durable. I would get a new mech if your happy with gearing
Only worth going 10 speed if you want to take advatage of the 11-36 or greater cassettes.
Nowt wrong with 9 speed, and still plenty of quality components to still be had.
I've been for a ride on the Quantocks today, my bike was 3x9 with 26" wheels, I used all the gears 44x11 to 22x32 although I did spend a fair bit of time in the latter.
It was fun and the world didn't come to an end.
Perhaps a new mech. is the way to go; any good bargains about at the mo.? All the 9 speed XTs I've found are pretty much the same price as the newer 10 speed ones.

Don't think that's remotely true
So can I use a newer 10 speed rear mech. on a 9 speed cassette with a 9 speed shifts; I'm assuming that the indexing and pull is dependant on the shift?

If you've not done them recently, new cables and outers will have a huge effect.

No.
Whilst the shifter does control the cable pull, the shimano 10speed MTB rear mechs and shifters operate a different pull ratio, so 10 speed mtb mechs aren't compatible with 9 speed shifters.
It may also be your chain and cassette that are worn rather than rear mech.
Or you've knocked the mech hanger slightly.
