Those temps are well within normal range and it's normal to feel some heat off the back of the iMac. Just make sure to keep the top vents clear from obstruction. Also keep in mind when comparing the iMac to the Mac Pro, the iMac is more like a laptop. It runs Intel's mobile version of the CD2 cpu and logic board. The fans in the iMac are more than adequate to cool it but making sure the fans are doing there job is another thing.
Also the CPU is the least of your heat concerns because it can operate up to 100C and has a safety shut down(forced sleep mode) if it ever reaches that temp. Though the other components may not be so lucky. As for heat problems in general I don't believe heat is necessarily the problem. I do believe it's better to be safe than sorry but the iMac is designed to run at these temps and if there is a hardware failure that happens to be evoked by temperature it may not necessarily be caused by heat itself but rather faulty components. With that said personally one of my biggest concerns is to make sure my hard drive runs as cool as possible. I try and keep it under 50C at all times.
Here is what I have my machine running at:
Yes it's my iMac 2.8GHz. I'm running Temperature Monitor: http://www.versiontracker.com/dyn/moreinfo/macosx/19994
You just have to go in and customize the settings. I opted to get rid of those screen windows and add all the sensors to the menu bar for easy access.
