I came at this from a roto perspective since the tool I use for this is roto based but I'll try to base my analysis on the implications of the numbers for h2h.
I projected this team using Rotowire's projections and my new Excel projection tool (thanks to GTWMA work with examining loads of 12 team standard leagues to find the %tile's for each statistic).
I projected full play time for all starters except for 121 a piece for Helton and Dunn. I gave no bench play time since my projections only account for 1 Util slot but this gives you more credit for Helton and Dunn than they should really get which is offset by the fact that I'd imagine Helton/Dunn gives you a better Util duo than a lot of other teams. I projected 111.8% full play time for all your pitchers to get it up to 1250 max IP. You actually projected for 1118 IP - if this is lower than your max you'll need to add pitchers and if it's higher you'll have to adjust for that accordingly.

I really like your team. You really followed my pitching approach - I'm always short on wins as well.
Everywhere else this team is stacked. You don't really dominate anywhere other than in batting average though and Dunn could end up dragging that down a bit when you give him full play time. But with this being h2h you've done exactly what you want to do - you have a solid chance of winning 9 out of the 10 categories every single week and a decent chance at the W's category.
