Unless the home equity loan is relatively small (under $40,000 or so), it is being counted as installment, like your mortgage. Paying down installment debt does help some, but the score impact is minimal.
Did you decide to get out of credit cards for some reason? It's true that they can be time bombs if not handled right, but because of that very reason, having revolving credit with very low usage helps your scores a lot. (Higher risk = higher reward.)
I have 5 CC's with over $50K in credit limit, but I rarely have more than $100-200 on my cards at any one time, and I pay them off before I ever have to pay interest. This has definitely helped my scores. EQ has increased 100+ points in 8 months from how I use my CC's.
