After the belts, consider doing a compression test to make sure it is good. If it is running slugish all the time, I suggest checking the catalytic converter. It could be partially plugged if you have been burning oil. Too much back pressure can cause these symptoms.
As far as the timing belt, you will need to remove the cover to check it. Also, based on which V6 you have, you may have a timing chain.
Let me know. Also, bad valve seals will produce blue smoke, but clean up after driving for some time unless the guides are really bad too.
