Narrative:

On departure from ted stevens international airport, a beech baron was cleared for takeoff in front of us. The tower assigned him a departure heading of 160 degree. We were then told to taxi into position and hold. The tower then asked if we could maintain visual with the departure aircraft and responded with, yes. The first officer was flying the airplane on departure and was complying with the knik 6 departure procedure. Upon contacting departure I reported that the aircraft in front of us was in sight. After rolling out on our SID heading of 190 degree, it became evident that we were heading for the aircraft in front of us. Departure was talking to another aircraft at this time and I was going to request a turn further to our right in order to avoid the preceding aircraft. Departure came on about this time and told us to turn right immediately to a heading of 270 degree. This was going to allow us close to the other aircraft, but not putting either aircraft in danger. Departure then talked to the baron, and about this time our TCAS went off, and I reported to departure and we ended up climbing through our assigned altitude. Departure then came back on telling us that they needed us back at 4000 ft immediately of which we complied. The flight then continued on normally.
