I'm not sure what you mean by you don't think it is working? What are you expecting to achieve????
If you have music and photos in the iTunes library on the computer - the only way to get them to your iDevices is to sync with iTunes.
If you just want to use iCloud and you have it all set up - I'm not sure what you are looking for and that is why I ask what you are hoping to achieve.
If you want to use iCloud only - you have to set up an account which you have already done. Then you go into the iPad settings>iCloud>and turn on everything that you want to sync to all of your devices in there, Mail, Contacts, Calendars, Reminders, Bookmarks, Notes, Photos Stream, Documents and Data - and Find my iPad if you use that. You also want to tap on iCloud backup>On so that your iPad will backup to iCloud.
Also tap on Documents and Data and turn that on as well.
The tap on Storage and backup and in the next window tap - Manage Storage - then tap on your iPad name - then turn on every app in the list to enable them for iCloud.
I dont know much about using Photo Stream, but you can find answers here.

I don't use iTunes Match for my music either. I still keep all of my music on my computer and I dont need Apple to store it for me at this time. You can read about that here.
