[Star Wars] I am a powerful Jedi Master and I want to kill the Emperor. How seriously should I take his Royal Guard?

well they are worth worrying about to some degree. They're better trained than any stormtrooper and they have minimum requirements in intelligence, height, build, experience and skills just to join the training program, and almost always have already proven themselves combat capable. On the other hand, they carry mostly melee weapons (force pikes and vibroblades) along with a small blaster under their robes.

The truth is though, if your strong enough to get through every other defensive measure up to the royal guard, they shouldn't really be an issue, and if they are, the emperor will certainly be able to kill you without too much hassle anyway. The guards equipment is largely inefficient to the task of killing a jedi and even palpatine has openly admitted that they're mostly there for appearances and intimidation to visitors. 

TL;DR: if you are strong enough to have any chance at beating the emperor they won't give you a problem. If they do give you a problem, you weren't up to the task in the first place.
