I've also just graduated college and I guess I can add my two cents (since I got 2 job offers one month after graduating yay!).
Don't bother with a title unless you're required to. They're stupid. Objectives could be helpful if you're aiming for a position in a large field, and it isn't clear from your resume what you're looking for. I was mostly applying for jobs in biology research labs, and it was pretty obvious that I was doing so since I had "research experience" as its own section. I was also looking for a job related to art, and I thought it would be better if I had some sort of objective listed on that. I tried to make it like my experience and knowledge in science would help in my artistic endeavors...
I mostly applied to jobs online, so the employers can't tell how long your resume is exactly, but keep it short and to the point. My mom even pared down my dad's 3-page resume to 1-page, joking that such a long resume would belie his advanced age.

Besides, nobody is ever special enough to deserve a resume more than one page long, LOL.
I suppose it depends on what kind of job you're looking into, but employers would ask for references
after they had reviewed my resume. One even wanted to meet me in person before bothering my references. So, I guess putting it onto your resume isn't something that you HAVE to do. Definitely ask your potential references before giving out their contact info. I recommend 3, for a good start.
And I don't know how important references are in general, but for me, glowing references trumped my so-so interview skills and not-so-hot GPA. In science, it doesn't matter how you look or how you project yourself onto clients, but how you work. Past professors will be able to tell your future employers about how hard-working you are and how good you are in lab better than a piece of paper, how you interview, and how you dress. Again, this depends a lot on the field, but it's definitely something to think about. One lab wasn't too sure about offering me a position, but then the coordinator contacted one of my references and then immediately offered me the spot.
I was really lucky though - I went to a tiny college and even my freshman year intro chem prof remembered my name at graduation.
So, I guess the most important thing you can do is think like your employer. If you were hiring someone, what would you look for? What would you deem important? And then tailer your resume/cover letter/whatever accordingly.
