I'm a North guy, & I don't have my contract on me but I'm almost certain the answer is yes. As long as it's the same airplane, you can move to another base no problem.

For your other question, I think DC9 initial training takes about 2-3 weeks not including OE. Full systems course plus procedures trainer plus Full Flight Sims will probably take about that. I think it's 6 sims or so. I'm probably wrong though.

When I requaled on the DC9 after my displacement I got a short requal which was 1 day of systems & 3 sims(including my checkride), but that was because I had flown it on the line in the last 12 months. They'd never do that on an initial qual!!!
