Lost Wallet and like to know what should I need to do

I am just lost my wallet on last Thursday. I reported to SSI department, DMV, and credit Bureau and cancel few my credit next day. In the wallet, I have student ID, IRS issue prepare #, SS, DL, membership accounts, some cash and gift cards ( for more than $300GC and less than $100 Cash). Are there anything I need to report? On today, I receive the evelop with no address and in there I receive DL, SS, IRS prepare #, insurance card, Bank cards and credit cards back,but no gift cards and one of credit card that credit limit is $8000 is missing. However, I am so affair since I know there is someone pick up and know my DL and SS #. I am just affair they will open accounts or loan since they have all my information and address #. Do anyone have something like me and what do you recommendation next? I don't really care about my gift cards so much, but I am affair of identity theft and it was very painful to go through to cancel debt. Are there anything you recommendation? Thank you.
