Gore,
I think the rules for a rough conversion of PC's from RM2 are in RMSS Spell Law. Also there is in the character generation section a chart that has all of the stats and there bonuses. On the bottom of the table there is a formula for generation the bonus for higher stats. I do not have my books or the PDF's with me so I cannot give you a page number, but if you cannot find it just say so I will go a diging for it.
