Reach actions only, & not opinions?

1)Does "Believing with you that" mean "Like you, I also believe that"?
2)Does "that he owes account to none other for his faith or his worship" mean "that the man should explain why he holds his faith or his worship"?
3) Does "reach actions only, & not opinions" mean "(legally) monitor and control people's action, but not monitor and control people's opinions (Freedom of Speech)"?

Background info:

In that letter, referencing the http://en.wikipedia.org/wiki/First_Amendment_to_the_United_States_Constitution, Jefferson writes:

Believing with you that religion is a matter which lies solely between Man & his God, that he owes account to none other for his faith or his worship, that the legitimate powers of government reach actions only, & not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should 'make no law respecting an establishment of religion, or prohibiting the free exercise thereof,' thus building a wall of separation between Church and State.^{http://en.wikipedia.org/wiki/Separation_of_church_and_state#cite_note-Jefferson11-15}
