yes to all :lol:

also there's no need to hack the webcam nor remove any filters!

Best results are gained with the removal of the IR filter + use of IR LED's.

Standard LED's can 'flood' it... causing all sorts of drama. I spent about a month stuffing around with a decent Logitech webcam, and in the end - the only way I could get it working decently, was with the IR filter removed and IR LED's added.

In the end, I got sick of it - reverted the webcam back, and brought a TrackIR.

actually the best way to do it would be to replace the IR filter with a filter that would block light. in any case it took me 10 minutes to make my first freetrack thingie (i've improved the technique over time after making 3 more for friends and upgrading mine :lol: ) and my webcam that also happens to be from logitech has given me zero problems using it with its IR filter in place. maybe you didn't tweak the exposure settings?
