I want to be able to generate enough power to run my laptop and keep a couple of lights inside the RV lit.1. Will a 100 watt portable solar array do it? Or will I need 200? (Let's assume that I'll usually have sunlight.)
You mentioned "fan" later in the post. A good fan on High for 12 hours will need 100W solar just for itself. Portable solar more than 120W becomes a pain. Better to permanently install 200 or 300W on the roof.
2. What's the easiest way to use the DC output of the panel(s) to light the interior of the rig (and maybe run things like a fan and/or the water pump)?
You don't understand how 12V system works. Your lights, fan and water pump are 12V wired to the battery. All you need is "more" 12V power at the battery. This is done by clipping crocodiles of solar output to the battery. There will be a small box - controller - between the panel and battery, to regulate the panel output. That's all.
If you're not sure how to, spend more and buy one of 100W solar suitcases. If you feel more confident, spend less and get 100W "kit" from Solar Blvd. Either one will include all solar parts - panel, wire and controller. With Solar Blvd kit you might have to make "legs" of PVC pipe to prop the panel up.
