Window coverings may not be the landlord's responsibility. If it is, then cheap blinds is all they have to supply. The rack in the oven is a different story. But the leaks are the big issue. Especially if you have to pay the water bill.
Az law is not very tenant friendly on this:
Housing > Landlord and Tenant Rights and Responsibilities > Arizona Residential Landlord and Tenant Act
If the cost of the repairs are less than half the rent, then you can advise the landlord that he has 10 days to make the repairs or you will hire someone to and deduct the cost from the rent. So you will have to get an estimate of the repairs first. Or if the problems affect habitability, you can cite breach of lease and move. The site I linked to has details on this.
