Yep, pretty normal - the only things that one could worry about being damaged at that tempurature is he hard drive, and it should have its own tempurature readout.
But yeah - 80ºC-90C is about the point where somebody needs to be worrying; a heatsink would be dislodged or a heatpipe broken. Or the thermal interface wore out.
To reiterate - your tempuratures are perfectly fine.
However, the MacBookPro forum would garner a lot more replies then ours, IMO.
