RE: Should custom work be done on the Tikka?
 

With the good quality scope, rings and premium ammunition (or handloaded with a combination or powder, bullet that is most accurate with this rifle), you don't need to have additional custom work to make the Tikka T3 a "tack driver". The hardware will do it's job, you mainly just need to concentrate on doing the rest practicing with it.
This is the most accurate rifle I've personally owned out of the box. I don't think you'll need to have the trigger adjusted either. It comes from the factory breaking at 3 1/2 lbs. if I remember correctly. It's a smooth pull and breaks cleanly. Enjoy, have fun with it. ;)

I just bought a Tikka T3 Lite in .243 with Tasco Worldclass 3-9x40 and it shoots like a dream this said it is my first gun

I would definately dump the cheap, supplied rings and get some decent ones (Talley, possibly the new Deadnutz, etc). You can adjust the trigger yourself ...very easily.

I have several head of big game at well over 400 yards with 3x9 or 3x10 scopes.For big game at 400 yards,I would never bother with such a big heavy scope.

I have a SS Tikka Lite in 243.It is the only rifle I have never had to do anything too.Out of the box,with the Tikka rings and Burris 3 x 9 x 40 it has shot five different types of ammo less that 1" three shot groups.I also had to order my Tikka as I am left-handed.Last year made a shot on a decent buck at 475 yards(lasered) and he went about 25 yards after the shot.I will agree with everyone else and say see how it shoots first and I think you will be OK with the Tikka out of the box.

says you have a 300wsm....if you want to reach out and touch something my goodness what more do you need?

My 270 model 700 shoots pretty nice at 200yrds with a 3-9 VXI...Right out the box...

Tikkas are already tack drivers, with a quality scope like the Nikon you have on it. You don't want/need to glass bed it, it's a free floating barrel and the mounting system holds it on zero once you get it there.
If anything work on finding the optimal load and bullet combination, which can have affect good or otherwise.
