Paint
Wash the walls to remove any loose dirt and grease. TSP (it is actually faux TSP) from your paint store mixed per directions is a good choice. When I have had to prep a smoker's house I have found Purple Power from the auto parts store to work better than just about anything.
When dry fill any holes, cracks, etc. with wood putty or joint compound. Sand with fine grit sandpaper--- 100 or even better 120 grit. Sponge off any dust one more time.
Caulk any seams between wood paneling and ceiling, baseboards and window and door trim with a quality paintable caulk. Allow to dry. You should also caulk any gaps between wood panels or planks that you do not want to show when painted.
Seal any bleeding knots or sap lines with shellac or a shellac based product like BIN. Make sure you have adequate ventilation as BIN is alcohol based. (Not that you should not have adequate ventilation with any product!).
Prime with a quality primer. I would use an oil-based alkyd product on wood if you can get it. A water based bonding primer will work too though. I like Benjamin Moore Fresh Start but like others here have often used Zinsser products and they are a bit less expensive.
Follow the primer with two quotes a quality latex acrylic paint from a paint store, not a box store. Pick the sheen of your choice but note that the glossier the finish the more the surface imperfections or, in your case, the wood grain will show.
Depending on how rough the grain of the wood, you may have to use a thicker than normal nap roller cover. Usually I would use 3/8"-1/2" on walls but you may need 3/4" or even more if very rough.
Use good equipment and the job will go much more smoothly.
