Your problem is that you have to steal a lot of items to make it worth it. You're trying to remedy that fact by asking for mods that make items respawn; however, that is not that simple. It has been done for Welkynd Stones, but it wouldn't work that well with clutter items standing around in the houses, because you'd have to edit each one of them (as far as I know).
So... I propose you try one of the mods that change the prices of clutter items. I'm using and loving this one: http://tesnexus.com/downloads/file.php?id=22089.
It may sound a bit strange, but I think if all the items have more reasonable prices and even robbing a pottery could be a good idea (which in vanilla Oblivion would amount to a loot of items worth 0 gold), that will make thieving much more fun for you.
