So, I've had my mind changed for me about the Master Specialist PrC. I'll drop the changes to it, so you can take it at level 4.
I couldn't find that Barbarian rage variant in my Unearthed Arcana book, but from your description it looks okay. Just provide me with a page number or online reference so I can give it the final confirmation.
The noncaster Ranger looks fine to me.
Those rules for Align Water look good too. It's like sanctify, but for water!

I think Fool was right about the Attack ratings; +8 if you attack only once, +6/+6 for Two-Weapon Fighting, and +6/+6/+6 for Two-Weapon Rage Fighting. The additional Strength from the rage basically cancels out the -2 penalty for taking the extra attacks. As for damage, as long as you're using the Two-Handed Fighting rules, you use your full strength bonus for damage with the primary side of the sword, and 0.5x your strength bonus for the secondary side. If you make only one attack with the sword, you can use it as a two-handed weapon (instead of treating it like two separate weapons) and use 1.5x your strength bonus for damage.
A handy feature of the program we use to play the game is the presence of dice macros; you'll be able to make a button each for pretty much any of your available attack styles.
I played a rogue once, who had seven different attacking macros, for fighting with/without Boots of Speed activated, or with different weapons, or when throwing daggers... ah, he was a good rogue. His damage output was ASTOUNDING. And he could flank on his own, and do short-range teleportation. And his journals were
wordy, as evidenced on the 7th post on
this page. His first journal takes up more space than my entire laptop screen.
And I'll try to get the server up earlier than usual on Saturday for practice, yes.
