This webpage shows how I've seen it done most of the time. For the lines you've given, you'll be using iambic pentameter.

*/ | */ | */ | */ | */
That <b>time</b> | of <b>year</b> | thou <b>mayst</b> | in <b>me</b> | be<b>hold</b>

I used bold to indicate the stressed syllables (/) and left the unstressed syllables (*) unbolded.

Answer 2

Rhyme scheme is indicated by letters. The rhyme scheme for these four lines is indicated like this:

ABAB

or

A
B
A
B
