Your questions:

We have received questions for advice on resumes....

what should be included?

1. how long should the resume be (does it really have to be limited to 2 pages when a candidate has 2 pages of diverse and interesting projects?)

Answer: 1 page for an entry level, 2 pages for most all others.  Projects and cover letters are not considered part of the resume.

2. do dates ALWAYS need to be included?

Answer: Yes, always include month and year on a chronological resume.

3. should reasons for leaving a job be included at the end of each job description?

Answer: No, unless it was because of a layoff and that might be considered an exception.  Save it for the interview.

4.  should references be included or only upon request?

No, again, save them for the interview or on the application.  The phrase is now outdated and rarely used.  It's kind of obvious you'll give them to the interviewer eventually, especially if you are under serious consideration.

5.  does a resume HAVE to have an objective (after all everyone wants to work for a "progressive company that values it's employees and clients")

Answer: Yes, but you should gear the objective to the actual position for which you are applying.  Also, the phrase "people person" is also over used.  Remember, you are seeking a position in the company, insure you also include a summary which indicates that what they're looking for is what you bring to the table.

Good luck.

Recruiter Chic nailed it head on.....good summary.  The objective (# 5) is very well put.  I'd also suggest you add a summary to your resume, encapsulating your background.  Again, Chic, good job.
