You probably know this already, but the adapters you have linked are for running JK wheels on a TJ. Is that something you already have (JK wheels), and want to run them on your TJ? Plenty of TJ owners have done this; it just depends on what your taste in wheels is.
The second link is for 33" tires on possibly TJ wheels, which would not need adapters, but may need spacers. Those are essentially the same as adapters, but have the same 4.5 wheel spacing for both the spacer and the wheel lugs.
