Welcome to the forum! Glad to have you aboard! wow 298 miles. From what you are describing you are good with maintenace. The B20 series engine that you have to maintain. A good example is the valve lash be sure you adjust it more frequently as these engines the exhaust valves dig into the cylinder head when the engine runs too quiet its a sure sign that the valves are too tight. Timing belt , tensioner & water pump replace it on the proper interval. As usual the other regular maintenance ATF be sure you use specifically for Honda as these Honda uses lower viscosity than those regular ATF, Power Steering Fluid be sure you only use Honda PSF as their formulation is close to Hydraulic fluid , Rear Diff fluid be sure you only use Dual Pump Fluid. Brake fluid flush or replacement. Coolant I would suggest to stick to Honda Coolant. Good luck on your ride!
