It's an ok class, but I wouldn't go out and get the book for this alone. There are a bunch of snazzy classes in there though (I'm quite fond of the Spellsinger (Excellent Countersong ability) and the Elven High Mage), but the best stuff is all the background material on the Faerunian races.
Be careful with the acquire Bardic Music ability of the Warrior Skald. Since it's a 3.0 bard prestige class, Warrior Skald grants nerly all the bardic music effects on its first level. Adjusting it to 3.5, you should allow the Warrior Skald levels to stack with bard levels only for uses per day and effective bard level for existing bardic music abilities.
Note also that bard spellcasting is not advanced with this class. Combining this class with War Chanter (CW) or can be pretty potent. Feats such as Snowflake Wardance (Frostburn) and Ironskin chant (CAdv) are worthwhile for such a character, as are Extra Rage (CW) and Extra Music (CAdv). There may also be some excellent goodies in the PHB2, but I don't have that book.
