Regaining lost levels in 3.5

[gadren]

The 3.5 rules are a bit vague on limitations regarding regaining levels lost from Raise Dead, etc.

When the levels are regained, do the characters have to retake everything they took before (class, skills, feats, etc.)?

Has there ever been any specific text on this published, even in a Sage Advice?

If a Fighter 6 loses a level, he becomes a Fighter 5. A Fighter 5 can, on leveling up, choose to become a Fighter 6... or he can choose to become a Fighter 5/Barbarian 1, or /Wizard 1, or whatever else he wants. There's no such thing as "Fighter-5-who-used-to-be-Fighter-6-and-will-be-again".

Does this apply even when restoring levels via the Greater Restoration spell?

Nope. Restoration (http://dictionary.reference.com/browse/restoration?s=t) means "a return of something to a former, original, normal, or unimpaired condition". That's going to return the specific original level the character had previously. Going through the Level Advancement steps (Player's Handbook, pages 58-59) lets the character pick the class they gain at the first step. If you don't go through Level Advancement, you don't ever get to step 1. Choose Class; instead, you just restore a former level.

Okay, so...
If a Fighter 7 loses two levels and becomes a Fighter 5, then levels up through xp and takes a level of Barbarian instead and becomes a Fighter 5/Barb 1, what happens if he then has Greater Restoration cast on him?
