One thing I noticed right off the bat, you might want to go and get some vines ties and secure that cane a litte better, the fruit weight could pull it right of the cordon, the cane breaks and then you lose the whole thing, just before your ready to harvest. Sometimes tendrils can grab ahold and save it, but, I would not risk it. Normally I wrap my cane alot tighter than that, with more wraps, and tie it tight on the end.
Hope this helps-John

I'm trying to recall how much my vines grew in the first 2 years. Mine has been producing a good number clusters since year two. Unfortunately this is probalby the first year that I think I know how to properly manage my vines. I should get some pictures of my vines so that see what happens when you don't know what to do from the start. You have go to see my trunks. They ain't straight.
Since your vines are still young, I would consider thinning 1/3 to 1/2 of the clusters if you have a good number of fruiting shoots. I would do some reading first though. Also, after removing the shoots from the trunk, how many fruiting shoots do you have? This might help determine how much to thin.
Take my comments with a grain of salt. I only have 4 years experience with *not* managing my vines correctly. Hopefully, this year will be there year I get things right.

Alot of vineyards drop ALL the 3rd leaf/year crop to allow for root and wood growth. I think that is a little over kill. My established vines I prune to 40-60 clusters/vine depending on the vine and it's location. So, I would say that leaving 25% to 50% of a full crop would be a good compromise.
But, after looking at the picture the first thing I would be doing is to prune all the suckers off the trunk and tie the cordon to the wire in aleast 5 to 10 places on each side. Then once the vines are pruned and tied I would leave the best 5 bunches on each side. Just as a note I read that you should drop your clusters before they flower/set the grapes. The research claimed that it didn't help with wood/root production if the clusters were dropped after the grapes formed.
Hay, YOUR plants look very healthy..... Good Job
