Agreed on a few points. I think Crosby is fine, and any field goal over 50 yards is bonus anyhow. The fact that he has misses from that distance suggests that the coaching staff actually trusts that he might be able to get it from that distance.
As to the holder situation - that actually IS very important. My son has been a high level kicker (he's 18) for a few years now, and his success really does have a lot to do with the holder. Yes, on converts and shorter kicks it's easy to cover up for the fact that your holder is not doing *quite* what you want him to do, but on the longer stuff where angle and velocity are a lot more important, the hold is also that much more important.
I don't really have any problem with Crosby this year so far.
Also, with the success over 50 yards, I think that Nonstopdrivel's take of at least 5 attempts is reasonable. 1-1 means nothing, 2-2 is fine, but a bigger sample pool is required to determine whether or not a kicker really is accurate at that great distance.
