I hope you did not try an update on a live store!! Did you update the aio component too? Your Joomla version is insecure, use J3.4.5
It sounds like a "typical" hickup of the JTableNested. Go to your menues in the BE and use the "rebuild" command
Those are all warnings or notices - but are not VM errors. You can turn them off - http://forum.virtuemart.net/index.php?topic=102555.0
Renaming your plugins/system/scriptmerge/ may help.
I have seen reports elsewhere that it is advisable to update Joomla language packs when updating to J3.4.5 due to issues which may affect menus.
Joomla language packs can be accessed through http://community.joomla.org/translations/joomla-3-translations.html
The image files could be too large (ie not optimised before upload) or you don't have enough server PHP resources. Also ensure that the server PHP has exif functions installed (check in PHP Information tab on Joomla/System Information)
