Hi and welcome
Seat post should stay firm as long as the clamp's tight...
8 speed cassette may require an 8 speed freewheel hub which may not be compatible with the wheel/dish? (not sure about this though...)
The barrel adjuster (twisty bit) could be replaced as they just screw out- you'd have to source a period replacement though...
Chain/chainring moving? Buckled chainring?
You could replace all the bits or go the donor route- it all depends on how much you want to spend and what's available...I'd stick with it and source the parts if I were you though as you have a frame you like and it feels good to ride...
Thanks dude, thats really useful and for the time being will just make sure the seat post is clamped nice and tightly. have done about 250kms and it hasn't caused an issue yet.
will checkout the freewheel hub situation. I do have a spare wheel although, just my luck, the spare also has a 7 speed cassette on it!
think might as well just replace the shifter at this point.
It does seem to run a bit like a buckled wheel might (probably about .5cm of movement side to side). hard to tell if its worse when more pressure is applied or if it is just constant. Maybe just dismantling and reassembling might help me spot if anything else is at fault.
