Ok I got a 94 RS, from a 1 owner. Got 116k on it right now. Car runs smooth even at 110mph

She said she had Acura changed the timing belt at 69K. Got new AC compressor on 2 years ago. Its an automatic.
So what should I do next to make sure its in top running condition? What Oil should I used? When should I have the timing belt changed again & what should I replace while having it changed.
Thanks in advance for all your help. I'm mechanically incline
