Hi, bn_bullet. Welcome!
I ended up with a set of bars and a set of turfs for my 2210. While I don't think it is necessary, it just worked out well for me because I already had a set of rear mounted bars when I bought my 2210. Depending on your snow removal needs, terrain, and your ratio of mowing-to-loader use, you will likely be fine with turfs.
As for the R4s, Deere does not offer them as a factory option on the 2210. Nobody has yet figured out why, and I don't know if your dealer can help you or not. I also do not recall anybody with a BX stating they have R4s either. Maybe the 26" R4 is not (readily) available /forums/images/graemlins/confused.gif
You may have read that I had a trans fluid leak shortly after delivery. My dealer took good care of me and there is a service alert about a condition where the toplink plate (they call it a hinge) can flex an immeasurable amount from pressure from a hydraulic ram mounted internally that serves the rockshaft. The first strike solution is a beefed-up toplink (hinge) plate which your tractor will likely to be shipped with. You could ask your dealer to ensure that this is the case. If your dealer needs a reference, you could tell him that there is a "DeTac" case from Delaware. DeTac is the Deere Technical Action Center (I think /forums/images/graemlins/confused.gif) where such issues are recorded and disseminated to the dealer network.
Other than that, it's a perfect machine for me. The loader is very capable, the 62C mower gives a beautiful cut (I got the mulching kit), and the handling is very tight for a tractor with this footprint. If you still have time, you might add the rear worklight kit for $35, or so. You might also see if you can have the dealer weld chain grab hooks on your bucket before delivery--also worth the cost if you can't get the dealer to throw the shop time in.
Have fun and be safe--not necessarily in that order. /forums/images/graemlins/grin.gif
