I tried to lay tile. I made several mistakes here. I was told it was ok
to
put it down right on top of the linoleum. It has always floated around.

The big problem though is around the toilet. The ring that holds the
plumbing for the toilet had rotted. I thought I was being smart and
bought
another ring, cut it, and slipped it behind the base (to keep the base
from
slipping below the floor line. I have always had trouble keeping it
sealed,
since.

Is there a way around not cutting out and reinstalling a new base for the
toilet?

When I install a new floor, should the toilet attach to the sub floor and
the flooring come up to the already mounted toilet, or should I mount the
toilet onto the new flooring (I'm thinking of tile or a floating wood)?

You will need to repair any failed wood substrate, add a new flange and do
your floor-covering.
Most modern toilets mount to the flange. You say your flange was rotten so
that makes me think you had a metal one. Is the pipe blow the flange lead or
plastic pipe? Or how old is the plumbing? A little more detail from you and
one or more people will post help.

I will add that if your wooden floor is not rotten there is a repair flange
available at full service plumbing stores that works fairly well.
