you dont need to copy it (and I wouldnt advice it either as it would most
certainly cause some conflict) but simply create a new plugin which will
extend it.
See
http://www.cartoweb.org/doc_head/docbook/xhtml/dev.newplugin.html#dev.newplugin.adapting.extending
simply add the replacePlugin function and the methods you want to override
or add some new ones.

Both are possible option but I would suggest use ajax and div elements (that
can slides from the bottom as you said).
See http://www.cartoweb.org/cwiki/HowToAjaxablePlugin for implementing ajax
behaviour.
This way you can handle as many "steps" in your wizard as you need without
having side effect on the rest of the map stats.

You want to start the wizard when the user clic on that button ?
Simply add a button input in your plugin template and activate this template
element from the renderForm function of the plugin.

simple example:
{if $wizard}
<input type="button" ... />
{/if}
in template

$template->assign('wizard', true);
in renderForm function

Have a look at other plugins to grasp the concept and how things works.
The schema http://www.cartoweb.org/doc/misc/plugins_diagram.pdf also helps a 
lot.

Oliver
