gingernut,
Welcome to the wonderful world of flying!
Just about everyone I've ever spoken to comes across this "plateau", it's certainly nothing to worry about. It usually happens shortly before solo - is that roughly where you are now?
I don't believe that poor coordination should be a big problem. If it was, I'd never have got my PPL, that's for sure! Many years ago myself and several friends all learnt to juggle - my friends were all masters within a few weeks, and it took me 4 months before I could keep 3 balls going!
You say your progress has been slow - how slow? I wonder if it would be a good idea to book a week off work, and spend the week flying 1 or 2 hours a day? At this time of year, you'd have to check the weather forecasts carefully (and I hope you have a job where you can change your mind about taking a week off at the last minute!) - but that's exactly what I did when I reached my "plateau". I flew for an hour a day, and then worked on my Air Law. On the Friday, I passed the Air Law exam, and on the Saturday I flew solo - and believe me, it's worth it!
There are a few instructors who read this forum that I'm sure can give you advice re. bumpy landings, but in my un-educated opinion, it's most likely to be because you can't see the correct picture for the landing, therefore you're landing too soon? The only solution to this is to keep flying, and eventually it will click into place. Some people say to look right down the end of the runway, or to look out the side window instead of in front, as you're in the flare - they didn't work for me, but if they work for you, great.
Most important, though, is to stick with it and not give up - you will get there in the end!
FFF
