This is one of those curious passages that calls for further examination. We might be too quick to judge here without knowing the fuller context. Is it something about these particular lame and blind? Is it that the Jebusites were using them as a defensive shield? Was this sanctioned by God? We are not told of David loathing lame and blind anywhere else in fact we see David going beyond the call for Jonathan's lame son.
I do not believe these to be in any chronological order. We know that Solomon was born to wife Bathsheba who has not entered our storyline yet. They may have all been mentioned together just to have them all recited in one place.
David as king of united Israel is shown going to God for counsel on who and when to attack. That does not mean that this is all that he goes before the Lord for. No doubt he petitions God concerning a great many things of national and personal importance. No doubt God is answering him in a similar fashion but, we are not privy to these prayers.
