It could also be that you just need to add Power Steering fluid to the car that can make a noise similar to what you are discribing.
sure! i have 19" alloy wheels on my 2000 cougar
Unfortunately the lug pattern is different, the wheels will not interchange. You can use Thunderbird or Cougar wheels.
about 300 at the block about 220 at the wheels
In most cases one of the differential units will be naturally lubricated, but there are some medical conditions that may interfere with this natural lubrication and so require a little extra "greasing of the wheels." If the units are similar units then lubrication will likely be required. If differential units are joined at a non-standard junction lubrication will also probably be necessary.

I believe that the 35th's came with 17 in wheels, which used a 215/50 tire.
2 front wheels 4 front wheel bearings 2 inner and 2 outer
It depends on what wheels your cougar came with. If you have the 15 inch, six spoke fan blade wheels, you need 205/60 tires, if you have the 16 inch, sport package wheels, you need the harder to find, 215/50 tires. 17 inch wheels were not available in '99 to the best of my knowledge. If you have trouble finding the 215/50/16 tires, both the more common 225/50 tires, and the 215/55 tires can be used without much problem.
The best way is to go to a junk yard and pull the disk brake assembly off of a Cougar, or a Contour/Mystique, the latter two will require you still purchase a Cougar specific E-Brake cable though. There's plenty of info on this conversion in the wheels, tires, and brakes section at the newcougar.org forums.

Could be a broken ABS sensor ring at one of the wheels
By gaining lift, adding lubrication, using wheels instead of flat bottom
