A slow rise is much better for a coin than a short pump, so I'm not worried at all about the price right now. If the roadmap gets completed then all of the features are bound to bring attention.

Also, do the Net Hash and Difficulty tabs at the overview section in the transaction explorer still serve a purpose or could they be removed?

They just show the difficulty of the last PoW block and the net hash of the PoW period. The difficulty will be updated to show PoS difficulty and nethash can just be an archive for people to look at if they wish to look at the nethash of the PoW period.
