Well, I like to cut my arrows as short as possible. I'm short, my bows are short, and I want my arrows to match. If you plan to hunt with this setup, and I don't see any reason not to if you are proficient with it. I'd shoot whatever you can get tuned the best and have the most confidence in. As I said, I like heavy arrows with lots of FOC. I don't get too hung up on the charts because most, in my opinion, recommend too stiff a shaft. If you can live with a bit longer shaft, I'd probably go with the 3555s. They are a bit under 500 spine, I think, so you will need to point load them some. Don't be overly concerned with speed. By compound standards, all of our bows are slow. However, for thousands of years, they have been fast enough! Make sure your bow is quiet (heavy arrows help that), and that you can hit what you shoot at. Pick a spot and put some venison on the table.
If, at some point, you decide you need more bow weight, by all means go up, but do it a little at a time. If all you are hunting is small game, turkeys, and whitetails, you won't need much more than what you have. I like 45 to 50 pounds. That weight gives me all I need to hunt what I mentioned above. At 60 years of age, I don't really think I'm likely to hunt much else, so I'm happy to stay at this weight as long as I'm able.
Shoot lots and lots of arrows at targets, especially targets of opportunity (stump shooting) to hone your skills and because it is a blast. Have fun because that's what traditional bow hunting is all about.
