Glad to see GD being helpful!
OP there is some great advice in here and you're already setting yourself up for a better result just by saying you want to get better and recognizing some of your areas you feel you need to improve on.
Before I was a Ret lad most of my raiding experience was as a Holy Paladin. I wanted to get better so I looked at what other players were doing to learn how to better myself. I would read theorycrafting forums and study fights and how to maximize every cast with the timings of abilities and positioning throughout encounters. For me I studied Diamondtear (imo still one of the best Holy Paladins to play the game) I would watch every Paragon kill video to try to understand why DIamondtear would make the decisions they did in those instances. These are just a few of the things I did at least.
Becoming a better player is a mixture of just studying what others do, practicing it, and straight asking people how they do things or why they do things. You can figure most things out on your own but if someone else has it figured it out it never hurts to ask. Most players are generally pretty happy to explain when you tell them you want to know how they got gud.
There are tons of player guides out there you should definitely check out. Follow some of this advice here in this thread :)
