But now that he is 2nd officer, should he be at ops?
No, there is no direct relation between the two responsibilities. One is a job description; the other is a description of one's place in the ship's chain of command. In fact, DRGIII and I talked about this and decided it makes sense to have La Forge as the ship's 2nd officer (i.e., third-in-command) from main engineering; if the ship suffers a hit that takes out the CO and XO on the bridge, and command transfers to engineering, it makes perfect sense to have the chief engineer as part of the chain of command to keep things running without interruption.
And, incidentally, that's the same set-up as what Kirk had aboard his Enterprise
: Scotty was 3rd in command after Kirk and Spock. Though he usually took over the bridge whenever Kirk and Spock were off getting Ensign Ricky killed.
