I have a handy flow chart for RFI location at:

This may help...

Hi Jerry.
The first thing to check, is if the "noise" is from your own stuff, or
outside you immediate control.
You can do that easily, by running the rig from batteries (internal or
external) and turning the house off at the main incoming switch.
If the noise level drop's significantly, then you're in with a fighting
chance of tracking down the source(s). Go arround unplugging/turning
off "Everything" you can find.
Note the noise level, then turn one at a time back on, and see what is
the main source.
Don't forget anything that is not on a plug-lead.
If there is no change when you turn your house off, then it's something
outside. A screened room won't help, as of course your antennas need to
be out in the open.
You might want to take a radio and antenna /P to wherever you are
thinking of building a new house, and do a background RFI survey, before
you commit yourself..

Aside from installing ferrite on all cables (not sure why this isn't
integrated somehow if it's that large of an issue) would having the shack
walls lined with a grounded screen help reduce/eliminate radio noise?
Is the cost/effort worth it?
My wife and I are planning to build a house in a few years and I'm planning
out my station.
Based on the noise issues I have and have researched it sounds like I need a
shielded room where all cables in/out are wrapped in ferrite and power is
routed through a 1:1 transformer OR true sine wave UPS.
Then I still have to deal with computer equipment noise and anything else to
get a clean signal where the ground noise is low.
