Invision Structure Help

I want to change the theme of my forum- I currently have phpbb2 and I want to switch to an invision skin- What should I be aware of- What do I lose- Do I lose template editing? Also, I see when I preview my forum that the structure is straight- Can I still change the hierarchy afterward? Please answer as soon as possible.

First, yes, you will lose the template editing (for the time being, anyway.. if they add it later). However, the Invision CSS is really easy to modify as it's all pretty self-explanatory on what you're editing.

Yes, you can still change the hierarchy (at least to my knowledge), although you'll be able to collapse the categories with Invision, if you or your members wish to do so.

Also, in the beginning of the new version, the header used to be stretched across the entire top of the screen as where the bodyline (ipbwrapper) was below the entire header section (which included the userlinks). Now, however, it seems that they have modified the wrapper/bodyline to be just like the phpbb versions (much to my dismay).

Also, the profile page layout is a bit different and the tabs for the members to edit their profile info are on the sidebar instead of on top, and accessing a members info is placed into a drop-down menu just above the member's avatar in their posts.

Really, with it still being a basic FM html code, there aren't really many changes other than the brief appearances here and there. All the editing (except template) is exactly the same.
