Developing a ticket system, need some help please regarding organic groups, amongst other things!

Hello all,

I've had a search around but I never seem to be able to find what I need.

I'm developing a website which offers a service similar to that of a ticket system. The idea is that companies request a certain piece of information by answering various relevant questions (using CCK). The details become a published node, which our admins and other users with the required permissions can view, and send the required information back to the client.

We've implemented OG as our clients, which are businesses, will have multiple employees working on projects. So the group will be the company, and users from that company will be assigned to that group. These companies (groups) and employees (users) are manually created by ourselves.

The site is nearly complete but is a bit ropey. Ideally I'd like to have it up and running by Friday so any quick responses would be much appreciated. There's a few issues I'd like to resolve but haven't the knowledge, so if anyone can help, then great!

Firstly, how can we, as the site owner, automatically grant our moderators (people who work for our company, not clients) permission as the managers of each group created? The standard with OG is that only admins become managers of a group automatically. I don't want to give moderators fully-fledged admin rights. But I do want them to be able to moderate group content and be able to access it.

Secondly, when we create a new user, we'd like to be able to assign that user to a particular group upon creation. So is there any way of getting some sort of option on the Add User page to assign them to the group there and then, rather than getting the site moderators to trawl through the groups section and add them there?

Thirdly, is there any way we can implement a node or something for each group which would contain their contact details, like company name, mailing address, telephone number etc?

Any help with these points would be really appreciated.

Thanks in advance!
