Should I stick to one Class/Build?

[Tamo 49]

Is it best to stick to a single Class or Build, or should I try to gear up a few characters?

That of course depends on your own preference, as some people prefer to switch classes around more. But at first it is generally better to focus on just one class that you know best, so you can get familiar with how the boss works, as playing a class you are more familiar with should allow you to pay more attention to the boss mechanics and get more comfortable with them. Also, fully mastering one class can get you and your group better results in a raid than trying to switch around multiple classes. As for the builds, again, at start, it is better to master one particular build, but as you progress, it doesn't hurt to learn all the other possibilities of what your class can do.
