I can only say based on my experience:
Must change the water pump or else they won't last long enough till the next TB change (at 210k).
Honda's belt interval is based on how long is the belt. Their DOHC has the belt drive both cam gear instead of the common 2 inner gear design of Toyota, so their DOHC belt can last longer (i.e. 1.5X teeth for N cycles vs only 1X teeth for N cycles), nothing magical.
Usually it is a good idea to change pulley and cam seal at the same time. I am approaching 170k and my oil seal is still perfect, so are my VC gasket. Make sure you use gasket maker around the cam loop sharp corners on the VC gasket, or else it will leak at those area, first hand experience here.
Most older Honda engine spin the opposite way as other make, so don't think about using the starter and a breaker bar to knock the crank shaft bolt off. You need a hex key with a hole (many people weld a 26mm bolt to a pipe) to hold the pulley in place, then use a 19mm bolt with an impact gun to break open the bolt. That is the hardest part. If you don't have the right tool, bring it to the shop, or buy a morosol crank pulley holder from summitracing.com
TB on Honda is one of the few things that I recommend people bring it to a mechanic.
The going price for labor only is $200, if you buy Honda parts from dealer, it is about $120-180. So $400 is about right.
