Testing Multiple Forms for Goal Tracking on GA

[jaffstar]

Can someone let me know if I am doing this correctly:

I have 4 x forms on a website. For example:

Small Widgets
Large Widgets
Medium Widgets
Giant Widgets

Each of the above forms are unique.

They all use a generic part 2, part 3 and part 4 (thank you) Pages.

I have set GOAL URL as PART 4 (thank you).

I have set for example: Small Widgets and REQUIRED STEP.

Does this sound correct?

Will Ga Automatically trigure conversion only when Required step is used?

If I want to track say, from homepage , all the way down to THANK YOU, would everything work providing I have multiple forms?

anyone?
