There are a wide range of options for leveling feet...depends on how much weight you want to support and how you want to mount the feet.
As for the concrete...are there any cracks which might indicate that the concrete has sunken over time in spots? There are inexpensive fixes depending on what you are filling but they can get a little time consuming and if the concrete is sinking, you should address that before trying to fill the low areas or it may be a wasted effort.
