Thank goodness for your wise words Green Goblin, I was really concerned with several of the posts.
Good to ask though - can't learn otherwise.
Energy management is exactly what it is in the smaller cessna's (et al)- each circuit can be different. Circuits should always be flown with possibility of engine failure in mind - too late when it has happened. Good practice for night circuits also.
Long time since I have flown the cessnas but I recall sideslipping with full flap prohibited in at least some single cessnas because
1. loss of elevator authority (due shielding)
2. gravitiy feed fuel system
