First of all, congratulations !!!
I fly the -300, -500 and NG myself so there may be very slight system differences but if you need any help/explanations etc. send me a message - I'll see if i can help !!!
I'm fairly new myself but a bit of a tech swat !
I agree fully with Ennie. Engines create HUGE pitch up. On a 2-eng go around, you may actually need to push forward slightly !!!
The rudder is very effective and as Ennie said, be very gentle with it !
I found a good way to work engine failures were to use hardly any pressure onthe control wheel and maintain wings level with the rudder alone - give you a good feel for it and easier to trim out then ! (must stress that that is my own technique though - one of methods given by instructor and works for me - not for everyone).
If you can get your head around the FMS and systems - the operation and sim sessions are much easier.
Good Luck
