3. In terms of affiliation with west coast groups that's a bit of a toss up. The Bloods in Baltimore are decendents of the Bloods from New Jersey (Started by OG Mack) and those bloods never had any West Coast affiliation. But at the same time, not to long ago a west coast representative of the Bloods was called over to come and shape up a local crew, later being captured and convicted for his crimes. So it's yes and no, but as a whole, most Blood groups are in name only, and have little to no West Coast connection.

As for the Bounty Hunters, they are more prevalent in southern MD, like PG County, and parts of Northern Virginia, but I threw them in anyways because they do have something of a presence locally. If you'd like to know more about the Bloods in Maryland I did write a decent paper on the subject a year back, I'd be happy to share it.
