As far as assist goes, there seems to be a few basic options. The wiki and a search of these forums can provide this.

1. Assist by name of the toon.
2. Assist by focus.
3. Assist by party leader.
4. The FTL system (Focus-free, Target-free, Leader-free setup, using Keyclone Hotstrings).

Looking at your macro on Hoofu's "0" button...
The last argument does not require nomodifier in the " ; [nomodifier] Healing Wave ", it would cast Healing Wave anyway.

Maybe try something like this:
/cast [mod:alt, target=player]Healing Wave; [mod:ctrl, target=Ognian]Healing Wave; [mod:shift, target=Ogniantarget]Healing Wave; Healing Wave

Assuming you always want Ognian leading, you can easily set up your keys for Hoofu to assist then act.
/assist Ognian
/cast Lightning Bolt

/cast [target=Ogniantarget] Lightning Bolt






Another option (the focus option) would be to use /Focus on the current leader.
Then your macro's for either toon would be...

/cast [target=focustarget] Charge
/cast [target=focustarget, help]Healing Wave; [target=focustarget, harm] Lightning Bolt

I'm not sure if you'll ever use that, but it allows for either toon to be the lead, with the other assisting.






I use option 3, with the party leader for assist.
It looks something like this:
/cast [target=party1target] Flame Shock

/assist [target=party1]
/cast Earth Shock

For a Party1 system to work, you need to set up basic paging when switching toons.
By default all of your toons start on action bar 1.
So make action bar 1 be your... assist party 1... and cast the spell action.
Make action bar 2 be the same spell exactly, but without the assist.
Then make it so when you change who leads, via the Keyclone PiP command and a WoW macro on the same keybind...
The wow macro includes /changeactionbar 2, on the new leader and /changeactionbar 1 on the old leader.

So if Shift F1 is Oggie's client in keyclone and Shift F2 is Hoofu's client then in warcraft..
Oggie has a macro on Shift F1: /changeactionbar 2. Hoofu's macro keybound to Shift F1: /script PromoteToLeader("Oggie") and /changeactionbar 1
Reverse the roles for Shift F2 with Hoofu's client coming to the front.





The FTL set-up requires a lot of configuration and set-up thought, but once done is a well oiled machine.
It makes no difference which toon is the lead as far as hotkeys go, each toon just has normal keys in each slot.
The hotstrings determine who should assist who, based on which toon is in the active window.
A lot of setup, but once done successfully anyone who has tried it likes it.




I'm not sure what you're looking for from a boxing point of view.
If you're casually leveling two toons together, a very basic set up will probably be as much as you require.
If you're going to do instances or pvp, keeping your focus free for either crowd control or a burn target is a good idea.
These forums have a lot of good ideas and the community is helpful too.




*Edit*
In my experience, its generally 2-4 hours. I transfered my 60 mage from account 1 to account 3 recently (so when the hunter team gets to 60, mage can join them).. running 4 new hunters with a 70 hunter.
The basic transfer stuff is pretty fast. Then you wait a variable amount of time for approval. It was 2 hours or so the first set of toons I transfered and 4 hours less then a week ago. Once approved, the final step is payment and its done basically immediately at that point.
