H22 swap question!

Hello everyone,
I was checking the possibilities of swapping an H22 engine into my 91 Accord LX, when today I found a local junkyard that has a 97 USDM H22 engine with only 20k!! miles for $1700, did I mention it only has 20k miles!?... but the only thing is that it's for engine only. No transmission, etc. They said it was a long block, aren't all H22s long blocks? or are there different types?
Anyway, I wanted to know which other parts would be needed to put the engine in? IE: which OBD/ECU, sensors (assuming they're bad/broken),etc, and if I can use the Accord parts like for sensors and mounts or will I need new ones? and how much would those parts cost. I know this is a really good price for an H22, especially a 97 USDM and with only 20k miles.. so I'm really anxious to know how much else I would have to spend to get this engine only working. I know all this has been answered in all the other posts, but I need a quick, concise answer as soon as possible so I'll know if I should go buy the engine before it's gone. Thanks!
