Welcome aboard.
I'd check the exhaust especially at the rear where the pipes meet the back box as it could be blowing from there. Mine was when I got it and I believe it's commonly where they first go.
As for the interior door pulls/switch housings then that too is common. Some people plasti-dip, some respray, some wrap and others like me have them hydro dipped (water transfer printing) which imo is the best option although the most expensive option.
Companies like this one; http://www.aquagraphix.co.uk/ , can hydro dip any parts you want in any colour/pattern. Typically you will be looking at £50-£70 to have the interior door pulls dipped in say a carbon fibre pattern.
