Hey there… tl;dr response - almost everything you mentioned is being addressed already and has been discussed by the devs - some, like Autoloot have been discussed into the ground and may or may not change based on the devs responses - its their game afterall so entirely up to them.
Specifics.
-
Music. This is basically because they have updated newer (better?) music in certain newer sections but havent done the same game wide so there are the situations where there is old and new music at the same time. There are dev blog posts about the Music if you check that section. Music is also subjective so they are never going to please everyone with their choices.
-
Combat - Again, the devs are addressing this one - in fact they go into some detail about combat feel, death animations and overall combat impact specifically in one or two of the most recent dev blogs - so this one is already being changed.
-
Autoloot - the devs dont want this. I agree with them but this is entirely personal and the devs will have to decide if they want to allow/change this.

Never really noticed this as a problem, except with the current lack of Map persistance where you have to fight your way back (being fixed in 0.9)… You can obviously teleport back to town from anywhere so I am not sure this is really needed.

Definitely disagree here. Most of the power offensively comes from skill nodes and this would make builds seriously OP. There are plenty of discussions on this topic on the forum. Skill points and nodes are currently designed to make you chose carefully on how the skill functions and limit you from taking the biggest nodes at the same time to prevent skills being overpowered. (*Some are already but thats a different story being considered by the devs due to LizardIRL and others feedback/testing). If you want more skill points, consider the +skill affixes on gear - you will see how added skill points can stupidly overpower certain skills.

Those iirc are all done by non-professional people (i.e. the devs and friends). Obviously this is something that can be updated when the actual content is more complete and fixed (i.e. lots of the text/voice needs updating).

Literally TONS of graphical updates are being shown off - almost every week by Mike in his streams. You can see them collated in one place by looking at the Dev Leaks post Dev Q&A - We've sprung a leak!
