My first issue was solved by editing the function input in the file class-html-helper.php. I have just added
case 'email':
between lines 77 and 78 and now I can set the input type to “email” and have the browser check for a proper email format. I suggest this change is added to the official repository as well.
For the second issue I have implemented a workaround by changing several hard coded text strings inside a number of files. It works for me now but a proper fix would pick the correct translations from the po-files instead of hard coding text inside the php files.
