If the cartridge was aligned by the dealer (I got an almost identical setup from Gene Rubin about a month ago) all you have to adjust is VTA, which can be done by ear/sight.
I am by no means a vinyl expert, but if you bought from a dealer, and they said that they mounted the cart, it's probably OK. There might be a jig in one of your boxes- a paper template that has a spindle hole and some lines. Put the jig on the platter and follow the directions
IF there isn't a jig, I bet there is somewhere on the net where you can print one...
As far as VTA
The story I've heard is that the "tail" end of the RE arms with an Aurum Beta S like to be LOW, since it's a pretty tall cart. I have only a few MM of clearance with the arm in the up position over a record. The needle, which is almost impossible to see, wants to be absolutley vertical to teh absolutely horizontal surface of the record.
Gene told me to look to the cartridge, specifically the top of the cart body, and try to "eyeball" that so it is parallel to the record surface while the arm is down.
good luck, I'm sure with some searching, you'll find much more info than this...
