Credit Score - Buying a house?

Im getting married Oct 3rd, 2010. From now until then my fiance and I will be looking to buy a house or a condo. My credit score is 750. Is that going to be good enough? Will the interest rate be worse because my score is lower than my fiance's?? Advice? How do I get the score to go up to 800 +?
