I don't think Lelouch is using Suzaku at the moment, instead it's a mutually beneficial pact. Suzaku gets the power he needs to liberate Japan, while Lelouch gets a powerful ally.
Opinions of each character are bound to change as the character develops. And judging from the opinions I've seen so far, a lot of people switched from hating Rolo / Suzaku to accepting them not because of Lelouch's acceptance of them, but because of other reasons. Rolo saved Lelouch at the cost of his own life, thus redeeming himself somewhat. As for Suzaku, his mindset changed drastically since the Freyja incident. So people who disliked / disagreed with his old mindset may find him more acceptable now.
Personally I don't care much for Rolo (his saving Lelouch was touching though). As for Suzaku, I found him annoying in season 1 because of his hypocritical nonsense, and frankly I thought he was psychotic for most of R2. :P But I'm beginning to like him better because he seems to have gotten over the past at last, and the ending of ep 21 was a nice surprise. :D
