Dual-Boxing WOTLK Disc Priest/Affliction Lock

Ok so i havent ever dual boxed anything before but i have my registered version of keyclone and i have messed around with 2 mages to see how things work and how i like it but the big question is when WOTLK hits i plan on playing both my characters to lvl 80 otherwise im to lazy and wont lvl 1 of them. So that being said i have 3 other RL friends who will be playing with me and we are gonna level or at least try to level by doing the instances. I need to be able to have a cast sequence of something for my lock who will be specced full affliction to Haunt. And my priest will either stay disc since the healing has been buffed or change to holy. I will be using my single computer with a 22 inch LCD and a 21 inch CRT monitor to run the characters on. I need help on how to set certain buttons and all that good stuff to make this easy on me if that is possible. I dont use the keyboard i have a Nostromo N52 game pad if that helps at all.

Thanks in advance

Bump before bed!

Look for abilities that would be used in conjunction with similar cast times.

.... This is off of the top of my head here ....

Priest: PW: Shield (Instant), Renew (Instant), Greater Heal (A bit longer)
Warlock: Agony (Instant), Corruption (Instant), Shadowbolt (3.0 seconds)

If you find abilities both classes would use simultaneously, you can put them on the same button or Key-Bind.
T could be "Lifetap" for the warlock and "/cast [target=warlock] Renew" for the priest.
Maybe Pain Suppression and Death Coil go together...

Another option is with castsequences for chains of spells. Not really sure what you'd want for the priest, but this could be your opening castsequence which gets pressed pretty much at the start of a given fight.

Warlock: /castsequence reset=combat/15 Curse of Choice, UA, Corruption, Siphon Life, Immolate, Haunt
Priest: /castsequence reset=combat/15 ,SW:Pain,,,,,,

Another option entirely might be...
Have the warlock spells in cast sequences on keys that the priest does not use much... say the Number Pad keys.
Num 1: Castsequence for opening
Num 2-5: Individual DoT's for recasting.
And the priest abilities on the normal cast bar, so 1-0 and - =.
Or alternatively, have the priests heals on the NumPad and the Warlock spells on the normal bar.

The priests heals could easily be (Change Regrowth to each of the Priests frequently used heals):
#showtooltip
/assist Warlock's Name
/cast [help] Regrowth; [target=targettarget, help]Regrowth; [target=player] Regrowth

So your priest will heal your Warlock's target (or if that's hostile, the target's target ie: whoever is being hit) on a keypress.
The priest will not need to target their heals.
If you go this route, you might want some pre-made heals, for example Self Heal on the Priest, irregardless of the Warlock's target.

With two toons, I'd pick a main which you're on mostly.
And then have an altenate, with their abilities either assisting off of the main or hitting specified targets.
If you know your group for sure, it can be /cast [target=tank] BigHeal.

Thanks ualaa for your feedback!

I think it's unlikely that such an open-ended (and somewhat confusing) post will be met with anything helpful. As a fellow new boxer I've found the wiki and Vyndree's Guide to Guides excellent beginner resources on just what is and isn't possible, and how to go about those things. I suggest you become familiar with those resources and return to the board with whatever specific questions you have left.
