53Kbps is the max speed of any dialup modem. Anything faster is based on
software compression and not the true speed of the modem.

Never ever is a tall goal. But for reasonable:
1. Make sure your phone NID box is grounded to the same rod as your
electrical service. You might have to move it or have it moved. If it is
NOT grounded now most (all?) local phone service companies will come out
and fix this. But beware that many older houses where the phone enters
at a location other than the power will likely have the phone NID
grounded to the nearest cold water line. Which many not be a real ground
depending on what has or has not been done to water lines in your house
over the years. And you might have to pay them for a change. This varies
widely by area.
Make sure your house power is well grounded. If you don't know how to
tell, call an electrician.
Now it gets harder. Get a good surge protector and use grounded outlets.
Plus EVERYTHING on your network and phone lines need to be protected.
EVERYTHING. This gets to be hard in most homes these days as you have
all kinds of things plugged into the phone lines. Cordless phones,
TiVos, Sat Dish Receivers, computer modems.
What is a "good" surge protector. The MOV based ones that you see in
stores have a problem. Every little surge they stop uses them up a bit.
But to tell if they are still a surge protector or just a fancy looking
power strip costs more in testing than buying a case of new surge
protectors. So get something from a brand you recognize that's rated
over 2000 joules. And toss it after 2 or 3 years or after a nearby
lightning strike. If you have lots of lightning in your area, replace
them more often.
Most lightning strikes that aren't withing a few 100 feet do damage by
raising the potential on the wires coming into a house by 1000s of volts
for a very short time. If the rise is consistant with all ways into the
house, damage is very much less likely to occur. This is why you want a
common service entrance for EVERYTHING tied to a common earth ground.
This way the spike comes into your house like a cork on a wave.
Everything goes up and down together. It's when you have things out of
synce that you get the damage.

This contradicts your goals.
