Based on the vagueness and ambiguity of the language of the lease agreement, all of these things do appear to be "interior aspects" that you would be responsible for. It is not often that we see a lease with such terminology. It would be advantageous to you to take the lease to a local attorney for a consult and to look at all of the other provisions of the lease, to see if it might save you some responsibility and some money. Good luck

It is too bad you signed this lease but you may have some help based on the vague language, as noted by my colleague. The general rule is that you are bound to the terms of the lease so if it says that you are responsible for repairs, then you are responsible. Now there are some limitations under habitability law and other matters, but those limitations do not seem to apply here. If the lease was more clear you would have few outs.
In addition to the issue of vagueness, you may have some defenses under aspects of depreciation. This may get messy if you make a demand for repair so you may want to try some amicable resolution first and if you can resolve this then get that agreement in writing.
