Do you have any reference for this fuel pump issue other than Dealer that replaced?
I checked part # at DIY and it show no change 98-07, but it could be wrong.
Edit: Spoke with Parts department at Dealer. They show a number of part number changes, through the years, but said it could just be price changes. They show difference # 98-02, 03-05, 06 then 07. Said 07 from 06 is different setup with bracket or something included on 07. So looks as if evidence is mounting, we have and issues with 06 fuel pump.
Side note: Toyota moved the charcoal canister to the rear in 03 IIRC, which could account for the 02 to 03 change.

I also have a 2006, replaced the fuel pump last year at 165k. I just replaced the bank 2 cat that was throwing a P0430 code, all O2 sensors were replaced and exhaust was checked for leaks prior to replacing the cat. It never really had a bad smell to it and seemed to run just fine. Also mpg averaged 12-13 and hasn't really improved since the parts were replaced.
Sounds like the old pump was making the vehicle run lean not flooding, this would cause it to run hotter and damage the CAT, makes more sense. You still haven't mentioned if the problem is when the engine is hot or cold.
Will an O2 Sensor that is not functioning properly necessarily cause Check Engine Light to come on? I'm not sure how old the Sensors are on my 2000 rig and my mediocre gas mileage appears to be getting worse so I am suspicious of O2 Sensors but my check engine light is not illuminated.

I change front O2's in attempt to improve MPG. I did this on a suggestion they may have weakened a little, but not enough to get a CEL. This was a waste of time $, no difference to MPG.

Having looked into the morning smell of fumes, versus after half an hour of driving, I believe it is the cats not being warmed up are part of the issue. But i believe I also need to tune her up and have the air pump looked at.
I think what you'll find is it's normal. I see you are in Glendale, not really close to me but you are more than welcome to check out my smell on startup.
It's a strategy, LEV certification of any type doesn't consider emissions during warmup when the 100 LCs were built.

I think you need to replace your PCV valve. Smell should go away.
What's the approximate cost to have a PCV valve replaced?
Part including new grommet around $20 from Lexus/Toyota. Only use OEM.
What about labor? How much time does this job entail (approximately)? Is this something a novice could take on relatively easily?

One more thing to check: Look in air box to check condition of air filter, while making sure Mickeys' not made a home there.
Dealer will charge you an hour $100. If you have the tools and time, you will take off the engine cover. Yours is the older kind so it's stuck in a grommet on the driver side valve cover. You will want to remove and replace the dried out grommet without dropping any of the pieces into the valve cover. Install the new grommet, stick in the new PCV valve attach the new hose and reattach the engine cover.
