Jenny,
Firstly I am converting from GA (PA28-151/C152/C172) and have about 5+ hours in the Jabiru so I'm not the best guy for pointers there. It might be worth posting a new thread, there are others that post on the various forums that would be far better at answering your Jabiru specific questions.
As I noted in one of my other posts, my landings at the moment are like a rabid dog with epilepsy. They are getting better, I'm using the rudder much more and the ailerons much less when landing.
Having said that, I have similar problems as you - left pointing, rounding out too high etc. I was with an instructor last week who said the left pointing is a Jabiru trait. Your feet, ie. precisely where you are sitting isn't exactly perfectly straight, it is off center in a Jabiru so the tendency is to set yourself up with the aircraft pointing slightly left. Sounded reasonable to me, but you may wish to confirm that rather than accepting it at face value.
With these lower inertia you have got to be on the rudder pedals all the time. And my usual instructor (many many hours in Jabirus (120/160/170/230)) teaches basically on (short) final keep it straight with the rudder and use the elevator to slow it down (or speed it up). On final most of the work is with your feet.
I've used FSX for quite a while. Unless you have a very sophisticated setup (including rudder pedals etc etc) it's not going to help much with landing. Where it will help is with procedures, so just starting the aircraft, doing the preflight in the cockpit, runup, downwind checks, shutdown etc etc. The iris simulations are quite good and the presentation of the panel is pretty good depending on what's in your aircraft. The basic instruments and switches are all correct. For about $30 for FSX and $28 for a J170 or J160 (if that's what you are flying) I'd say it's worth it. It's not going to teach you to fly though. You may also wish to look at XPlane, there is a free XPlane J160 aircraft and XPlane costs about $60 so, in the wash, it's about the same. You can get a demo version and try it out with the default aircraft.
