Currently the long term support (LTS) version 2.9 and the what ever the current release version is are supported.

There is a good chance the answer is yes! If there is a feature you would really like to see, come to the https://blenderartists.org/t/bake-wrangler-node-based-baking-tool-set/ thread and discuss it.

First check out the documentation at bake-wrangler.readthedocs.io, also note that everything has a tool-tip if you mouse over it to try and explain the function. I have created examples in the documentation and will continue to add them as needed.

If you still can't figure it out, have a look at the https://blenderartists.org/t/bake-wrangler-node-based-baking-tool-set/ thread and post your question.
