Hopefully, last day of "catch up."
Chronicles seems to just hit the highlights of 2 Sam 8-9. It leaves off the charming story of how David lined up the Moabites. Then, using a cord, he measure off thirds. Killing 2/3 and letting 1/3 live. Sort of an amped up decimation.
Again, there is a story of Israel reaching the Euphrates. This time making the people their vassals, rather than just raiding parties sort of dominating the area as in earlier version.
It is very noteworthy to me that David--who we think has a historical basis--is not killing everyone like Joshua--who we think is not historical--did.
Final story is David reaching out to Saul's family. He finds Mephibosheth and gives him Saul's land. Mephibosheth is disabled, not having the use of his feet. It is a detail that is mentioned, but plays no part in driving the action.
Psalms 50, 53, 60, 75--I read them. You'll have to believe me. Psalm 50 is interesting because it starts out saying how God doesn't exactly need sacrifices, but then instead of taking the typical turn to commanding Israel to care for the poor and the widow it says that good people do sacrifices anyway. The others were unremarkable, IMHO.
