From a Heroic TR 1-20th level perspective these rings may be helpful as well as there are versions for levels 3, 7, 11, and 15 and are very well rounded...
Gear-wise what I did was farm the Tier1 of the level 15/16 versions of both rings and then upgraded them to level 20 based upon Heroic challenge rewards while leveling from 1-20... At 20 I then started running Epic versions of the same challenges to upgrade each from Tier1->2->3...
EDIT: For more details on the level 3-16 versions and how to get them you can use the following links from DDO Wiki:
