1) That's UD box Row 1, you'll have very good seats with no obstructions, IIRC. 2) Never been to Yesterday's, I'm partial to Mullen's because it doesn't get as crowded as early as the others and I know one of the owners. 3) That's a long trip from Wrigley to the Cell via the red line, I wouldn't think it's worth the trip but I've never went inside there. There are decent shops around Wrigley for memroablilia. 4) I don't think the heckling would be too bad. Unless it's a rival like the Sox or Cards, it won't be bad but don't underestimate the douchebaggery of Cubs fans as there's plenty of them out there.
