Good to hear your SG is almost great
About your PO4...
Is yours a reef tank? If so, I understand you want no measurable phosphates
If it's a FOWLER you should be OK, but the phosphates may create algae
Plus, they will eventually build up in your rock and sand. Then you'll have fun getting rid of it
And as far as having your SG tested @ the LFS goes, unless they have a way to bring the water back up to your tank's temp, don't bother, but definately have your hydrometer tested again, and your other params too
I'd hold off on the fish until you find out where you truly are @ with your alkalinity
And not to harp on you but, buy a refractometer before you spend money on fish
Maybe you can find a used one here on the forums?
