Mike,
I'll do my best!
1. Yes, the take off trim setting from the loadsheet is set on the ECAM 'F/Ctl' page using the trimwheel after engine start. A typical figure for a full aircraft is around .7DN, but if your machine is set up for 4UP, then set that.
2. It is a little more complicated on the Airbus mcdu and involves creating the waypoint and then entering the vertical and speed constraints. Let us say you are 100nm south of Sprimont and have been cleared to SPI and to climb to FL350 to be level 50nm before SPI. You now need to create a waypoint 50nm S of SPI. The easiest way to do this is to define it by 'Place/Bearing/ Distance' (PBD). So on the mcdu's scratchpad, write 'SPI/180/50' and insert that into your flightplan, using the left line select key (LSK), where it will show as 'PBD1'. Using the right LSK, select PBD1 and you should see the Vertical Revision Page which will give you an 'Alt Cst' box. Write 'FL350' and line select that box and the task should be complete. If you wish to put a speed constraint in as well, that, too, is done on the Vertical revision page. Remember, vertical revisions - right LSK, horizontal revisions - left LSK.
3. Landing the Airbus feels the same as on a conventional aircraft. You do not notice the pitch down effect as you approach the flare.
Hope this all helps,
Cheers,
