May I qualify to apply for citizenship? Thanks a lot!

Although your green card is based upon your prior marriage, your showing proof of abuse and having lived in a shelter would go a long way to convincing a naturalization officer that your green card was legitimately obtained and should not be questioned again in the naturalization setting. Changing addresses and not informing U.S.C.I.S. is only a non-favorable factor if it was done intentionally. A tax transcript or other proof of having paid taxes is not required except in situations where individuals have worked in this country and are supposed to have filed tax returns. It would not appear to apply to you unless you had other income of a high enough amount to require reporting.
