Chashmal,
First, let's learn some jargon so we can confuse each other in the same language.
"VTF" = Vertical Tracking Force, sometimes referred to as just "tracking force" or "downforce". It's what you meant by "tracking weight" (though scientists/engineers would correct your use of the word "weight", since that's technically inaccurate).
Whoever told you Rega doesn't "honor" antiskating is clueless. Every Rega tonearm includes an antiskating adjustment. Your Rega manual, using British terminology, calls it a "bias" or "anti-bias" adjustment but it's the same thing. On an RB-300 it's adjusted by sliding a small button along a slot in an extension of the arm base (beneath the arm tube when the tube's in the arm rest). Toward the base increases antiskate, away from the arm base reduces it. Try various settings, from none to maximum.
Palasr added some valuable tips, but since much of this is new you do need to build a knowledge base or pay someone to do it for you. Most on this (and other) forums prefer/enjoy doing it themselves, and certainly that is the path to maximize performance. Vinyl playback is not plug and play, as you see. Neither is it set and forget. The perfomance of cartridges (especially) changes over time, with the weather, etc. If you rely on someone else to set up you're at the mercy of their schedule, not to mention their prices.
You can learn all this by reading and doing. There are many good sources online, including the FAQ's at Vinyl Asylum, Vinyl Engine, searching this board, etc. For an organized presentation in one place, consider Michael Fremer's DVD on vinyl setup, available from many online retailers. Well worth the time and investment if hours of online reading isn't your thing.
