Forwarded Records usually happens when the table doesn't has a clustered index, so the first option is to create a clustered index and only if isn't possible then you should go for a REBUILD.

avg_fragmentation_in_percent it's the index fragmentation level and depending on the value of this columns the recommended actions are:
If avg_fragmentation_in_percent > 5% and < 30%, then use ALTER INDEX REORGANIZE
If avg_fragmentation_in_percent > 30%, then use ALTER INDEX REBUILD

The "Forwarded Record Count" could cause fragmentation? or is an entirely different problem?

Yes, it can cause and that's why a REBUILD can solve the problem but only with a clustered index you'll be sure that the problem won't appear again in a near future.
