I like the raise to 5K.
Since it's 1/2 of our remaining stack or so it shows we are committed to this pot (with stacks as deep as these maybe "committed" is the wrong word - how about "dedicated?"). However anyone calling has to assume that we'll be putting the rest of our chips in on the river. And they should probably assume we're calling if they raise.
Our raise may look like we have a set or other big hand and are concerrned about the two clubs on board. There's also a slim chance that if the CO just calls us that he'll bluff at a 3rd club assuming we're afraid of it.
