In a climb it is strange to get anything over redline, but I try to climb out as close to 67 knots as I can get in the 152. If you are flying straight and level you should be able to exceed redline up to about 2800rpm. I don't know about a dive, I have never gone into one with a high power setting. As for a climb rate of 1100ft a minute, this sounds about right, in a full power climb with low weight you can get around 1200ft to 1500ft a minute. Now if you are heavy it is normally around 500ft to 900ft a minute at lower altitudes.
