Virtually zero cars at shows need no work. with that said, I would certainly attend as from your pictures, I'd say you are ahead of 80% of the cars I see at shows.
Besides, shows are more for meeting and greeting new and old friends to discuss your favorite hobby.
If anyone badmouths your car, (and people do for some odd reason), just smile and say 'enjoy the beautiful weather'.
As far as rain or hail goes, it sounds like you are 15 minutes from home. You should easily be able to beat any severe weather that pops up in the clouds on the horizon.
Couldn't be any better circumstances in my opinion.
And maybe you will get a little more motivation to finish some of those 'small projects' before the next show.
