You didn't give the engine or transmission.  I found with our last two
V-6 Accords, it takes at least 12,000 miles for the engine to loosen
up and start giving the best mileage.  With our 2003 V-6 we get around
26 in mixed driving, and a consistent 34 mpg on a trip.

I can't find the installation instructions for the fog lamps on the
current generation Accord, but for the '99 is was a pretty difficult
chore.  Involved removing the bumper, cutting plastic, etc.   The list
price on the lamps is $330.  You can buy them on line for around $236,
but assuming the dealer is going to charge you list, that's $170 for
tearing the front end of the car apart.  Sounds reasonable.

Yes, they should be pre-wired.

You can visit several web sites and look at the instructions as well as
the price for the fog lights. Click on the link below and browse to your
make & model > Look under Exterior > more..  Looks to be pain in but to
install....  http://www.handa-accessories.com/accord.html

My suggestion, and I'm 100% serious, is to forget fog lights
altogether.  IMHO, they're the most misunderstood accessory in the
automotive world right now.  All they're designed for is visualizing
the edge of the road when there's fog so thick that you really can't
see through it, and almost no one living outside of London or San
Francisco or places like that has ANY legitimate reason to have them.
It's terribly unfortunate that they started putting them on most
vehicles in the US where the ONLY function they serve 99.9% of the
time is to put TWICE as many lumens on the retinas of the people with
whom the user is sharing the road, making it more difficult for them
to see and making it MORE likely that an accident will happen to
someone.  Where I live in the midwest, it's especially aggravating to
be driving down suburban streets where every unaware SUV driver has
his or her ********* fog lights on for NO reason and aimed right in my
eyes.  He cannot see the road one iota better, but I can hardly see it
at all.  I think they're as ill-advised as people driving with cell
phones plastered to their faces.

You do NOT need fog lights.  That's the reason Honda doesn't make them
standard equipment, even on EX V6's.  Please give consideration to not
installing them.

My Accord I4 gets about 20mpg on pure city... goes up to 26-28 on highway.

You didn't say where you are, but the U.S. Accord fog lights are round
and butt-ugly in my opinion.  The Aussies get very nice
parallelogram-shaped ones that I'd easily pay $500 for.  They match
the front end much better.

There is some pre-wiring, but it doesn't help much.  Lots of cutting
and messing around, and if you make a mistake you've really screwed up
your car.  Get it done at the dealer if you decide to do this and
aren't really really (I said really) handy.

I had fog lights included in my final purchase dickering for my '04 Accord
(well, not full cost, but substantially reduced).
They are not round, but flat oval - and they look fairly decent on my black
EX.
I would not have wanted to install them myself - although the kit comes with
a template for where to cut out the plastic bumper facing, I would not want
to be the one messing it up and having to replace the bumper.  I still
haven't figured out how to replace the bulb if/when it needs replacing.
They are a full 55W light and do provide a lot of extra brightness on the
road when the fog is thick.  Unlike most fog light equipped vehicles whose
owners run them constantly because they look "cool" or whatever, I only turn
them on when I need them.  Oh ok, I do have a small weakness to relatiate
for a few minutes when some idiot follows me for miles with his on and let
him pass.
