Cymbidium cleanup

[Afid]

I recently got a large Cymbidium (NoID unfortunately) as a gift, and I'm thinking it could use a little bit of grooming. It is currently potted in a 10" plastic pot (in what I think may have once been a bark-based media). As far as I know it has not been repotted since it was in this pot (at least 3-4 years ago, probably longer). I also recently noticed a few scale insects on it so I will need to get rid of those too, which means possibly removing as many of the old leaf remnants as possible so they can't hide. Currently I am thinking I will pull it out of the pot, remove all the dead leaves, and maybe divide it or at least take off some of the old bulbs. I would probably put it in orchiata bark. I have very little knowledge about Cymbidiums and would love any advice people have as far as what to do with it, thanks!
