Pitcrew is a great shop, worth a drive if you have time but maybe an hour from the city give or take.
If you're confined to the city Palace5 is totally fine just not as big/old as Pitcrew. There's also Art under Pressure on U st? Not sure if they still exist. Skate/Graf shop I guess that's Bureau now. Shaw is fun, I think bridge spot is pretty much gone, there's one by RFK stadium (maloof), nice parks in the suburbs--Walker Mill and Laurel probably my favorites. If you skate transition there's Green Skate Lab in Brookland, a pool coping DIY bowl that's always open; and a wooden/pool coping (I think) bowl near Union Market that's open sometimes.
