From what I've read, it's about 13 ft lbs, but some people have reported that the bolts snapped (broke) using that spec and that just making them snug is good enough. Do not over tighten the bolts! You will be very upset if you break the bolts, so go easy.
Normally you don't need the sealant as long as the mating surfaces are very clean/smooth (not scratched up). You can use sealant if you want, though, as it seems to be popular with most people. Use a very thin layer, since you don't want that stuff mixing into the coolant. Two videos I saw both used sealant with the gasket. If the mating surfaces are smooth, I'd personally not use any sealant (as I already mentioned). You decide.
I highly recommend you use an Aisin waterpump. I believe the part number is WPT-007.
It makes sense to me to do the two bolts in the middle first, then the outside bolts in a criss-cross pattern. One video I saw said to do the outer bolts first, then the two inner bolts and to put black sealant on the bigger of the two bolts. I still think it makes sense to snug the two inside bolts first, but that's just me. Perhaps get all the bolts in there to make sure everything is lined up, then snug the inside bolts, then the outer bolts.
