Is this normal ?
toilet:
The cores did change from your 800 MHz (spitfire) to 1.3 (morgan) and the electric requirements are higher. I believe 1.6V to 1.75V along with 5W more of power to dissipate. Although 58C is high, I don't think it's anything to worry about. My duron runs around 54 with a stock AMD HSF.
Lapping involves sanding / buffing down the top of the cpu core to get a more level, smoother, and closer contact with the heatsink. Same with the heatsinks to remove the ridges in the metal and eliminate air / grease pockets.

I recently upgraded my system to a P4 1.8Ghz on a Soyo Board.
And the temp program that the board came with reported the the cpu was 74

If its not done correctly you can actually make it worse. It shouldn't be necessary unless your trying to get crazy with your CPU.

It might be neccesary if you want to improve cooling and still use the factory fan and heatsink. They're often ridiciously out of tolerance. I have access to a granite surface plate so that makes lapping relatively easy. You need a PERFECTLY flat surface and a fine sandpaper. Place the sandpaper on the flat surface (a sheet of glass works fine for home lapping) and then place your heat sink on that and gently sand it. You'll quickly notice if there's any high or low spots by the sanding marks. Sand until the whole heat sink makes contact with the sandpaper. I use 600 grit! You could probably get away with 300 though.
