4 - Fix up the issues with Unity and the marketplace. Whilst the software is the singular most important thing for most, you need to get your house in order first. There are only a few issues here, but they make a big big impact.

5 - Commit to a release schedule, fix a date and then stick to it. If something is 90% done - sorry but it does not postpone the release date. Don't let the softies give you the date - choose a date and tell them about it - remember - you are the manager - not them. You see more need to maintain control.

6 - Prioritise what gets fixed first - if some things are simply so broken that you will not get around to fixing them up for 3 months - pull them from release, it hurts reputation more to have a half baked attempt released than it does not have it not released at all, if you are under resourced, you need to accept that no matter how you dress the issue, you cannot achieve everything. It's simple and quick to remove modules or comment out features in code. You need to be bold here. This is where the Gannt and shit list comes into it's own as it will help highlight high risk items.
