X2 on the any solid glass arrows. I have tired the yellow jacket shafts. They work well and are a little stiffer than the regular white glass ones. But to me they were not worth the extra cost. They are more geared towards the compound shooters with high poundage bows. Stick with basic whit shafts.
AMS saftey slides are a must on all my arrows. #1 for the saftey end of it, they prevent snap back, which could be life endangering. #2 Because you get better arrow fight with them, and #3 because they keep the line at the rear of the arrow when retriving the arrow from the bottom or even when pulling in a fish. this keeps the arrow inline more with the sting and applies the most torque to whatever it is your pulling. Important when you miss and stick an arrow into a unseen log on the bottom.
As far as broadheads go. I personally have had the best luck with muzzy heads, the pirana heads work well too. For general ever thing fish, from 15" gar to 50lb big heads they work great! Unless you are targeting strickly large fish, I would stay away from the larger broadheads on the market. Unlike in bowhunting, while bowfishing you do not want a large hole in the fish, a large hole will cause more pull outs that result in lost fish that swim off and die( and are always found by someone who will protest our sport) To keep pullouts to a min, I use the muzzy heads and bend the barbs down to the shaft as flat as they will go while still retaining the ability to flip them around for easier arrow removeal. The basic muzzys come with two different tip options, the carp and the gar. The differece is minimal on these and I use both. The carp tips work best on fish but take a beating while fishing around rocks. Luckily they are easy to resharpen with a file. The gar tips take a beating a little better but are harder to sharpen and they tear a bigger wound channel though the fish. Lately I have gotten away from the gar tips unless I'm fishing alot of rocks and have only been using the carp tips with good succuss.
