First I'd make a few phone calls, check prices and installation cost at other shops in your area. Your new gasket should be OK, if you've purchased it from a reputable vender. Remember if the glass installer breaks the glass it comes out of his pocket. The other note I'd like to make is $76.16 for a curved windshield sounds kinda "cheap" and $110.00 to install seems kinda high. Actually if you turn it around it don't seem like a bad price at all???
