I was given a healthy bush in a container this fall, it got exposed to a freeze. Now the leaves are dead. Brought inside, do I take off the dead leaves myself? Sinc3 it is tropical does it also help to put a container of water next to it?
The container of water won't help much. You should wait until right before the new growth comes back to cut the dead growth. This article will give you more information: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/hibiscus-container-care.htm
