I'm sure that there's a "Honda part numbers explained" on the forum, but otherwise google would find it.
Let's look at the part number in the last link in #2, which is 53601-SEF-E13
What I said in #2 is potentially misleading, "53601" = "power steering box/rack complete" but you'd need to be careful because if you started looking at Civic's then you'd probably find that the same part also begins with "53601" and I wouldn't expect a Civic "53601" to fit an Accord (though you never know).
What I am saying is that, since the body-shell of all 7th gens are the same (from B-pillar forwards) then I would expect that all part numbers beginning "53601" for any 7th gen Accord should fit any 7th gen Accord.
But, if you want to be more certain, the next part "SEF" is more specific to the car model, so any 53601-SEF is the same whatever the year.
However ......
Here is the link for the Tourer version of your car

part number = 53601-SEG-E05
But this is certain to fit your car because, from B-pillar forwards, there is no difference mechanically between a 2008 2.2 SE Sport Saloon (aka CN1) and a 2008 2.2 SE Sport Tourer (aka CN2).
i.e. from B-pillar forwards SEF mechanical parts, and SEG mechanical parts, are the same.
Furthermore, by extension, I would expect any steering rack on any CN1 to fit any CN1 or any CN2, and vice versa.
