It depends. If you are talking about "the year's best game," there's an apostrophe. If you're talking about "two or more years," there is no apostrophe.
No, the sentence "She has almost 30 years experience" does not require an apostrophe after the s in the word years. The word "years" is used as a plural noun in this context, describing the duration of experience, so no apostrophe is needed.
The correct possessive form of "two years" is "two years'."
If there is a possession being signified, then yes. Example: Last year's numbers are better than this year's numbers. If there is no possession, then no. Example: These last years have been the best of my life!
No
