You may first want to inspect the base for fracture(porcelain is strong but it does crack fairly easy)and if appears in good order,turn off the water supply,flush the toilet.Ok?Now wet vacuum the remaining water out of the tank and bowl,remove the caps at the side of the base(if they're still there)loosen the nuts,remove them and slowly remove the tank and bowl.Ok?That gooky stuff at the bottom of the base and floor is what's left of the wax ring.Scrape or do what you will to remove the residual wax from the base and from the floor.The part that the base attaches to is called the flange.the top of the flange should be even or just below even with the floor and should be free from any debris or cracks and the threads on the studs should be undamaged,straight-up facing the ceiling.Provided the base and flange are ok,set the toilet back over the waste pipe(flange-hole)to determine if the toilet is sitting flush.If all these things are a go,go to the plumbing supply and get a new wax ring,place it firmly on the bottom of the base,set the unit down over the hole,making sure the studs align.Ok?ease yourself down on the toilet and let the toilet wax ring conform to it's installed position.Make sure your fill valve is on securely.Alright,go ahead and turn the water back on and that should do it.NOTE:if you did find damage to any of the components, of course they need to be replaced,and having a helper sure goes a long way.I also saw that you asked about the tank base leak.Same steps to remove the water,loosen the nuts,remove the tank,replace the rubber gaskets,(I have learned the hard way that it's better to replace them than to assume they're going to be ok)then line the tank back up on the base,finger tighten the nuts on evenly,and then firmly tighten them but don't over tighten.A turn and a half ortwo past finger tight should do it.Hope it works for you!
