1st thing is to clean that throttle body with throttle body cleaner, should be nice and shiny. This is the most common fuel robber in TB's. Removing it to clean it is best, but not critical. Careful, the butterfly is very sharp and will cut you.
2. Replace your spark plugs with A/C Delco 41-103, these will give you better gas mileage and better idle than others.
3. Replace your 02 sensor that's upstream, in the engine compartment. Try to stay away from Bosch if possible.
4. Make sure your air cleaner is clean
5. Make sure your tires are at the correct pressure.
6. Replace fuel filter
7. If you really want to go the extra mile, spend $9.99 on a can of Seafoam and put a 1/3 can of it in the brake booster vacum line, this will **** into the intake and clean the deposits out. The other 2/3's I usually put in the gas tank, so replace your fuel filter AFTER you have run the Seafoam through it. Otherwise it will clog up your new filter with the gunk that it cleaned from the bottom of the gas tank. Look up Seafoam on the net to see how it's done.
These things will help you go the pump less often.

I would check the catlic converter to see if its not blocked, best thing to do is to go to a exhaust shop and they can do vacume test or tempreature test.
