Rassal, yep they added the PVP checkboxes after the last update. To resolve the problem, just delete eq2ui_examin.xml from your custom UI directory. The only drawback to this is you'll loose the ability to quick broker search off emaine window titles. Nighfall has been updated so Pieces should follow eventually
Zetler, you can edit _Fetish_mainhud_cures.xml to add/remove any spells you don't want attempted. The code required to automatically select only those spells available to the current class is much more complex and would bloat the UI.
Health bars change colors normally, green at full health to red at less than 20%. Sry, but no I'm not changing the background color as this would cause readability issues when the bar changes to that color.
