I have created an installscript project using InstallShield 2010. I gather info during the install process in the method "OnFirstUIBefore()". But when the actual install of the software is happening (i.e. when you see a progress bar and it is copying over installation files) I would like to do some actions based on the user input.

My 2 questions are:

1 - How do I hook into that actual part of the install process?

2 - If any issues arise, how would I then undo what I have done? Can I store somewhere what custom things I have done?

Well you don't typically hook into the actual installation portion like that.

Instead, you would add your custom actions to the OnFirstUIAfter() event, so you already know that the files themselves have installed successfully.

Ah ok, thanks.

So, in my custom action how would I throw an error that will do any rollback? So that all the files are removed, and the install is cancelled?

There are no custom actions and no rollback in InstallScript projects, these are MSI functioniality.

You can use Feature event handlers (see help topic for details) which get called before or after a specified feature is installed.
