To fletch your own is very, very simple. All you need is the fletching jig of your choice, vanes of your choice, and glue of your choice. It will take a few arrows before you really get the feel of it, but it truely is quite simple.

Wrapping arrows has benefits. First, and most importantly, it makes your arrows look REALLY cool. We all know in archery it's not how good you are, it's how good you look doing it!

Glue adheres better to wraps. The finish on most carbon arrows doesn't promote good adhesion, which is why it is critical to clean the shaft properly first. There are only 2 negatives to wraps, as I see it. First, if you need to replace just one vane, it's a little tricky. I just strip the old one off and put the new one on in the same place. It doesn't look as good, but it performs equally. Second, it adds weight to the back of your arrow. If your FOC isn't negatively affected by that, it doesn't matter.
