I had less hours than you when I started my sim training, and my experience was on a turboprop less than 12500Lbs, and I didnt find the training that difficult. I am sure you will be fine.
For the landing the call: 50', 40', 30', 20', 10' is helpful, take the habit to flare depending on the altitude call if you previous airplane you flew is smaller.
The engine failure requires quite a lot of rudder compared to the smaller aircraft I flew, and if you have an engine failure at V1 rotate, take 1 second or 2 to set your rudder by looking the runway centerline, instead of rotating immediately and losing the runway heading.
Anyway with one engine you acceleration rate is quite low, you will not really go far above rotate speed in one, two or three seconds. You instructor won' t even notice it, and you will make safer departure. That is a tip, and just a tip, nothing written in the boeing manual and documents. If not sure just follow the Boeing procedure.
