Hi

no the alt will need to have the follow macro

1 - on your alt create a macro :

/focus Party1
/stand
/follow focus

and bind that to a key - also sets your focus to your brain which is nice

or use twobox toolkit which will set the alt to autofollow, details of this and other addons are at : http://www.dual-boxing.com/wiki/index.php/Addon_Codex

For the spread out macro when casting: mmm I only ever spreadout when showing off in town for general pve I don't bother as it's not necessary for most things.

For the heals, bind a heal macro to another key or use a modifer - personally I go for separate macros.

For all your macro needs http://www.dual-boxing.com/wiki/index.php/Macros it's all in there so just decide wether you going to use target or focus for everything and copy/paste away
