Language selector

Hello,

I hope this kind of questions is in line with the support you provide, please let me know if it's not.

I installed a fresh wp in English using the Glamour theme http://mythemeshop.com/themes/glamour/

I also uploaded the Hebrew language file from a native Hebrew wp.

1. My aim is to have a site with Hebrew as default and only language to the user, without "heb" in url as prefix or suffix - is this possible?

2. How would I proceed to always have an English dashboard?

3. Which language selector Eng/Heb would you recommend so both English and Hebrew show up for development?

Thanks
Israel
