Tactics for new German players. Boom and Zoom?

I am working my way up to the first BF109, and want to prepare myself. Each time I try to dive on enemy targets with my HE-122 series, I get over-compression and have a really hard time pulling out of the dive. I cut my throttle a bit to reduce this on the way in but inevitably I am going 500kmph and am just locked in.

Anyone have any good videos or tutorials which would help me? I understand German planes have a higher skill cap later on and would like to get on the right track early on.
