Foaming and splashing will oxidize the beer quickly. If your beer has that much sediment in it, it's not ready to keg/bottle.
If you rack from above the sediment, you should not have too much hop debris in your keg. I just kegged 10 gallons of dryhopped IPA and even with an ounce of leaf hops in each carboy, I didn't get more than a couple of particles in my keg. Careful racking is the key. I move the carboys at least an hour or two before racking, and then rack from the middle and lower the racking cane as the level of the beer lowers. You want to put the end of the siphon at the very bottom of the keg, to prevent oxidation. Splashing at this point will ruin the beer quickly.
