I'm going to ignore the blinds and the UTG limper for a second.
Given the following ranges:
Here is the flop equity graph for T9s against those ranges:
And here is the graph for 34s:
So if you are playing T9s because you think it gets you into profitable situations on the flop, I think you should also be playing 34s.
It looks like you will hit the same number of flops with 25%+ equity with both hands, but you will more often with 34s hit flops that give you 10-25% equity.
The closeness of the two graphs though I think helps to show how much more important postflop play is when it comes to situations like this.
Addendum: That's not to say that preflop spots are marginal so it doesn't matter if you play them or not. If you are a much better postflop player than your opponents, then it IS important to play every marginal preflop hand so that you get yourself in a larger number of non-marginal +EV spots postflop.
And if you want to see how unconnectedness affects your equity:
65s:
64s:
63s:
