Getting ready to do a complete tune up on my high mileage 98'. What's the best brand for replacement Cap/Rotor/Plugs/Wires. Used to be Accel was pretty good but it's been so long since I've worked on a gas engine, I don't know...

Anything else I should consider replacing or looking at besides the normal maintenance stuff?

I'd Recommend Accel. I ran there super truck tune up kit in my 98 and it was great. only $70 bucks with tax and you get everything you need, including a smooth running engine. Dont use Bosch anything on a 4.0 Ignition wise, I've found it causes a bad spark knock. Don't know why it does but 4.0's hate Bosch plugs.

I use MSD in my cars, but I use Borg Warner stuff in the Jeep

I went with the Summit Racing tune up kit and champion coppers. My jeep has never ran better.

Im running an Accel cap, rotor, and wires and i would recommend them to anyone. The quality seems to be much higher than some of the other brands and the cost is very reasonable.
