Question on Bender Card

[MooseWithFleas]

Hey guys, newbie here. Go easy on me

Been a long time reader on here and have picked up some nuances on detecting fakes, trimming, and grading in general. However I am still very amateurish and would like a second opinion on a card (and third, fourth, fifth if possible!). This is my first T206 and I've been contemplating the deal for a good 3 deals now reading all the information I can. After scouring the site for 7 hours last night, I figured I might as well join the fun and discussion.

Anyway, here's the card http://cgi.ebay.com/1909-T206-Sweet-...76135275677884

Questions I have are:

1.) Is the PSA slab legit?
2.) Is the grade of a 3 under-graded, fair, or over-graded?
3.) Is there any signs of trimming or something else fishy with the card?
4.) How screwed am I that the monster has a hold on me before I buy the first card?

I know I might be overpaying on this card a bit, but Bender is a Philly legend and would be a perfect start to taming the monster. I haven't yet decided if I'm going to fully go for it, but I'm sure you've heard those words before.
