OK, New year - new plane for MP...

A Bf109 E3 for starters but I know sweet nothing about these fab ac, particularly the weapons and belting.
1. From the threads I have read the ideal power band for these ac is at 2400 RPM but the prop pitch lever seems to have to be 'jiggled' to change the prop pitch. Is that correct as it seems to require a lot of 'jiggling'?
2. Any advice regards the weapons load outs (MG's and cannons) and convergence setting for the wing mounted guns would also be welcome.
3. Bombs, this is what I really want to have a crack at using in MP for the ground targets and there are two types available so any advice on this aspect will be also welcome.
Thanks......
