When you say the phones don't ring, are you referring to the multi-line sets, the analog sets or both? Since you have initialized the database, remember that only extension 100 will ring on incoming calls, so some programming of the CO lines will certainly be required.
You may also need to identify the station type. It's been years since I worked on this system, but I know that other systems that were similar in architecture had this requirement. Check the manual under station programming, specifically on programming page B to see if there's anything there about station ID.
The ring generator only applies for analog (single line) telephone sets, so this would not affect ringing on multi-line sets. Have you tried taking a known working single-line set and connected it directly to the blocks?
As for the outgoing "dial 9" issue, you probably have more CO line ports than you have actual lines. Place the unused CO line ports into trunk group 0 and that should solve your outward dialing problem.
