I don't have any advice on gear as I've just joined to research for a cycle I plan in the future.
That being said, if your joints are bothering you, I'd run to GNC and pick up some Tri-Flex. It was recommended to me by a few competition lifters after I started experiencing some joint pain/stiffness. After about a week I noticed my wrists and elbows felt a ton better. Mentally, its relieving for those heavy lifts too. I'm not going to say it'll help you 100% but it helped me and for less than $20 for a bottle of 60, I believe its worth a try.
