I've never liked the idea of 'hitting' a hardened steel, bearing component into place. They can (and will) crack, or chip if you get it wrong.
They should be an interference fit, so the size difference is only minimal (0.05mm?).
When we fit bearing components on site work, I warm up the press fit component to about 80oC and just place it into position. When it cools, it is tight.
The last couple of crown races I've put on, it did the same way but tapped them into their home pos. using a steel tube to press against the non bearing surface of the crown ring. (dont strike the crown ring directly with a hammer). I actually used the tube as an anvil and tapped the underside of the steerer tube with a soft face hammer. It worked ok and nothing got damaged.

.....should this be in the Workshop??

Yep, I have a crown race setter which I bought after I buggered a Campy Record crown race by trying to install it with a wide screwdriver and soft blow mallet. D'oh. The crown race setter comes with a bunch of fittings to make sure you put the pressure onto the right part of the crown race so it doesn't chip, crack, bend or just get messy.

I had no need to hit mine actually and simply pushed the fork into the frame and managed to get it onto the fork enough to be able to use the top cap screw to pull it down into place. I think i may have been lucky as i hadnt cut the fork and had heaps of top spacers but it worked. I dont know that i will have the same luck removing it so will probably have to use the LBS for that

Not too up on my Rockshox stuff but have had someone offer me a swap of my as new 2010 Fox FIT RLC's for a Rockshox RL

Whats the go with them? are they the bottom end of the scale or are they a decent fork?

I had a look at their website but its hard to tell if they are entry level type fork or not
