Trying OG 7.2

I am attempting to retro fit an existing site (configuration detailed below) with Domain Access and Organic Groups.

The existing site for anonymous users is and must remain the default domain (Domain id =1). The second and subsequent domains are intended ONLY for authenticated user with various roles.
Domain Access is operational with a drop-down selection list enabling movement between domains. So far, so good.

I have designated five content types as group nodes, adding four fields (Group, Reference, Registration and Visibility) to each content type and manually setting the fields in the existing nodes.
Additionally, I’ve designated 3 content types as group content and added the appropriate fields.

Again, so far, so good.

I have used panels and created a panel page with variants for each Group Content type. The panel page accepts an argument (Node Id). I plan on using QuickTabs to display the various views of group content views. The Group node is being displayed in a QuickTabs block on the panel

Issues:

Each authenticated user is affiliated with a default group in their user profile (a node reference field added to the user account). A) When the user logs in, he/she needs to be redirected to the Organic groups interface with their default group displayed (Hoping that a rule can do this). B) When the user clicks on the “Home” menu option, he/she needs to be returned to the OG interface with the default group displayed.

I have identified several tables which appear to be used by Organic Groups (see below). Some of the tables have a field called gid, which I assume stands for “group Id”. The problem is that, in no table can I find records for my group nodes where the node has both a nid and a gid. The OG table has no records whatsoever. Since this is a retrofit situation, do I need to create records in this table “manually” or via a script of some sort? Or, is the OG table, and, perhaps some of the other tables, leftover from the OG 7.1 version I initially installed? Since a user will be able to join multiple groups I had planned on having a block “Joined Groups” as a part of the OG interface to enable the user to switch between groups yet remaining within the panel page by use of the group type based variants.

I know these issues cross module boundaries but any thought on the general approach I’ve outlined or on the OG portion specifically would be greatly appreciated
