Should I cut off the yellow leaves?

Yes, once a leaf is fully yellow, it will not turn green again. You can snip it off to help the plant focus energy on new growth.

Is my plant getting too much sun?

If the yellowing is accompanied by brown, crispy patches, it might be getting too much direct sunlight.
