Hey Johan. I was in a similar situation not long ago.
I highly recommend the level 85 irons. From your current Blades they are a small but noticeable step forward, and they will help with the consistency you are missing out on (speed 4.2 and 3.0 forgiveness). The general ball flight/dynamics is great.
For drivers, you should consider the L85 Cally (282 yds @4.2 meter). There really are a lot of options as you stated, and if you wan the slightly cheaper club then there is the L88 Cally; just bear in mind this one has higher trajectory and a little less control.
Concerning wedges, there really isn't a whole lot in the 750 credit range. At 895 there is the max spin, and at 995 the mid tier Clevelands. The L31 64 degree Cleveland goes 60 yds, while Max Spin has a 75 and 60 yarder. I would say the Cleves are worth the extra 100 credits as they are quite well rounded; slightly better meter and forgiveness are of more use than 5 dots of spin which is rarely needed from 70 yds out.
As for putters, I too have used the L19, and I am not sure which of the high end putters suits me best. I just tried the L86, and it was good, but I think I prefer the feel of the L77.
Of course, you can determine what you need to improve your game better than I can.
Cheers.
