NL10..Top set, too greedy on river?

[1tripz1]

Just wondering if, as no draws get there, i should fire less on the river? Sucks if i pushed him off a hand by betting too much. Just to add id lost a pretty big hand before so thought i could push it to make it look like i was steaming, but maybe he doesnt notice this.
