I always hold Vx (except maybe with nervous passengers) until I'm clear of
surrounding obstacles. This also helps keep me in practice for short
fields. Then I generally transition to Vy until pattern altitude or the
fence to reduce the noise footprint and get some wiggle room if something
happens to the engine. After that, I drop the nose to 80 which I might do
sooner at an uncontrolled field with traffic.

Anything between 70 and 85 is "recommended" in the POH. There is only
performance data for 73 and slower.

Climbing at the speeds given in the Cessna POH for our 172 N are not a
particularly good idea.

Well, I'd hold the recommended speeds until I was assured of not hitting
any terrain.

Also attentitive to Vy makes a big difference when you takeoff from
elevations
higher than what you find in Maine.
