Default Sump Pump Discharge Questions

Hi -

I recently bought a house with a flotec pedestal pump in a basement
sump, and a terrible leaky flexible hose that the previous owners ran
to a sink when needed. Based on last spring, the basement rarely
floods - pump only ran after extended rain - at least two days
continuous, heavy rain. Don't know about spring thaw - moved in after
that.

I'm considering replacing the pedestal pump with a submersible (same
brand, same hp 1/3).

Also want to install permanent discharge. Was planning to use the
inexpensive flexible black plastic stuff for the run up to the sill,
then put PVC through the sill, and outside. I bought some 1 1/4" PVC
at home depot (they were out of elbows for 1 1/2". )

Here are my questions:

1) Submersible vs pedestal - any reason not to change? 1/3 hp enough
for this kind of intermittent running? Rise is about 9 feet.
2) PVC - Okay to use 1 1/4 ? I've noticed other posts seem to
recommend 1 1/2". Is there much difference?
3) I'm a bit nervous about drilling through my sill and siding (vinyl)
- any special things I should know before I do that ? (Plan to use a
hole saw on a corded drill).
4) Okay to let PVC run on surface downhill and just empty behind a
hedge down the hill several feet? Some folks seem to be saying the
discharge will smell terrible and mess up the lawn in the area it
dumps. The gutter goes in the ground and I assume either runs to sewer
or to drywell. Guy at home depot said don't tap into that or I might
overflow the calculated capacity for that system.
5) People suggest various vacuum break systems - some say drill small
hole just above check valve, others suggest adding T outside with
riser - do I need the latter?

Thanks all for any help.
