the main issues with h22's in 5th gens is the internal/external coil thing, the ecu pin swaping (gotta swap pin A6 and A11) and vacume lines .
having a 96-97 accord makes it kinda hard. you have to get a skunk2 wiring harness adaptor and convert it to obd1 and change a few wires around in the engine bay.
if you wana keep it obd2 the only motor that will plug in is the 96 h22a the 97+ h22 ecu has immobilizer and has different pinouts for the ecu.
the exhaust is also an issue, you have to cut the exhaust b/c the h22 header is about 16 inches longer than the accord header.
for power steering you have to get a custom line made and i hear you can use a 97 prelude line, but only one person that i know of did that.

ok, I avoided most of these problems when I did my 97 Accord swap. The internal/external thing was a problem when I had a JDM H22 in my car. However, I ended up getting a USDM 98 H22A4 so I didn't have to mess with that wiring. The ecu I got with the motor had the immobilizer programmed into it. I hear there are shops that can take it out but I haven't heard of any that have done it successfully. My fix was to use a JDM P5M which is exactly the same as the USDM ecu minus the immobilizer. Plugs right in and its OBD2 so no adapter necessary. Ok, I had to go to the muffler shop to cut the exhaust and move the cat back....can't avoid that. As for the powersteering line, the 98 Prelude line bolted right up to my 97 Accord steering rack and that bolted right up to the 98 Prelude p/s pump. NO problem what-so-ever. I've seen people mate the top part of a prelude line to the bottom part of an accord line also. I know one guy doing a 94 swap using a prelude line but he had to rebend the line to bolt up to the accord steering rack. As for belts, I had to replace the a/c alternator belt with one a little longer. I ended up buying a bunch of sizes and returning the ones I didn't need. This was my 3rd engine and I've done enough swaps into 5th gen accords to know what works and what doesn't so I learned all this by trial and error.
