With regard to your stage 1 kit, the alloy inlet / freeflow will fit although the freeflow will possibly be a little on the restrictive side for a 1275 metro. medium bore lcb is the usual choice on that one but it's not life and death to get the car up and running.
The air filter probably won't fit depending on what style you have and the needle definitely won't be suitable. Further than that, it depends exactly which larger carb is fitted, there's quite a range of options.
The Metro and Mini engines are the same, different cam (but Mini's alone ran loads of different ones anyway) and the early 80's Metro's had bigger inlet valves in the head (35.6mm as opposed to 33mm) and the heater port was blanked.
If it's an original unleaded engine, as opposed to a converted unleaded head then you should have an electronic ignition (I think).
In all honesty, unless it was MEGA cheap any checking should of probably happened already before parting cash. But it's not always an option.
Personally, if you're not in a rush to fit it I'd consider getting it (or doing it yourself) refreshed. Pulled apart and anything worn replaced etc. Have the head decoked and smartened up at the same time, maybe a cheeky deshrouding and a skim.
70k is edging towards rebuild territory anyway (for good power) might be ideal opportunity to do it now while you don't 'need' the engine.
In terms of further tuning, as long as it has a fast road type cam fitted then any of the usual options can be done with the engine in the car.
Considering you're going from a 40'ish bhp 998 to a 60'ish bhp 1275 you shouldn't be aching for anymore performance for a while at least.
With a refresh of the engine, the bigger LCB, cam, RC40 (1.75" is ideal), 35.6 inlets and some light porting on the head, once the needle and the dizzy are matched you should be looking at 85+ happily.
