As for your choice to upgrade to 80g for 2 oscars you will need larger. I would forget the 80 and go 130 ASAP. as you wish I will not preach about water conditions but would say read up as much as possible on the site. oscars are nothing like guppies by far.
i agree with marcus. save yourself some money and skip the 80 gallon tank. in another seven month or so your oscar will be full grown and an 80 jsut wont cut it. get the 130 and avoid the upgrade. as for your 2 strong filters, i hope they are. oscars are probably the messiest cichlids out there and filtration is the key to keeping them healthy and happy(along with tank size). a water test kit is also a must but since you are an experienced fish keeper ill assume you already have one.
as for pairing you wont know until they reach sexual maturity and that happens when they are anywhere from 1-1.5 years old. so just because they are playing nice together now doesnt mean they will later. once maturity hits all bets are off. if you are lucky and have a pair things will fine but if you have 2 males then things can get a little tense. oscar are territorial so space is your best defence against aggression but like i said this wont really come into play for about another year so no point in worrying about it now.

never known guppies fella, i meant green terrors, so please dont belittle me
if you are an experienced saum keeper then you should know that juvies often get along until maturity hits then become aggressive. so from what i gather your really only looking to see if you have a pair of oscars and what size tank they should be kept in and these questions have been addressed.
