No. You may want to keep speed down to min flaps up if you have big turns, otherwise 250 below 10 is usually flown, but ATC has discretion to let you speed up below 10 to 300 or so, and are often quite happy to let you do so, but now in busy terminal areas only they want you to stick to 250.
Either will do. Nobody will grumble at you if you do 1000' AAL OR equivalent position. Take your pick!
