I was hoping that someone would be able to translate these sentences for me, both into literal (word for word) and into overall meaning. Any help is greatly appreciated as I would hate to make a cultural faux pas.

1. Ты выйдешь за меня?

2. Хочу, чтобы ты стала моей женой

3. Я предлагаю тебе свою руку и сердце.
Всё, о чём я молю Бога - чтобы ты сказала "Да!"
Будь моей женою!

Any advice on a better way to say these sentences such as word order or maybe different words to better make a point is also greatly appreciated as I am only learning Russian now.

Thanks in advance.
