Facing your target:

Learn when to spam your follow key and also have a movement key only bound to your clones so they can stop moving to cast. When you need to change your clones' direction, hit /follow, walk a few inches and you can make your clones face any direction you want. It takes a little practice, but once you get it down it's second nature. I'm always insta-ghost wolfing and moving backwards, then make my main run through my clones to turn them around. It's a handy skill to learn.

FTL will fix your clones just standing there. With FTL, when you mouse over to the other window, that character becomes your 'main', and all remaining clones will move and cast based on that 'main'. On another related note, if I lose toons (especially in AV) I usually suicide and take as many Alliance with me as I can, that way all my girls rez at the same graveyard and same time.

Healing:

Since people think if they take the main out a boxer is worthless, They're always going after my 'main'. I have Lesser Heal bound to F1 and Chain Heal bound to F2. When I hit F1, all 5 toons lesser heal my main (Siaea). When all toons are taking damage, just make them all chain heal.
