The washer drain must be 2" pipe and have a trap. Any drain line must slope at least 1/4" per foot with no low spots. A washer drain hose has a U shaped end that hangs in the 2" stand pipe, you can not just run a hose to a drain. Gas lines are usually black iron up to the appliance, then a valve followed by a flexible gas line to the appliance. I would put a cutoff valve at the beginning also for ease of installation. From your description, the run will be short, so 1/2" pipe is sufficient. Basic to gas line installation is to make certain there are no leaks. Use a good pipe compound or the yellow teflon tape. Some guys use both. Shut the gas off, then starting at the furnace install a tee and a cut off valve for the new pipe. Reconnect the furnace and you can turn the gas back on. From that new valve, work toward the dryer. Usually exact pipe length is not critical, so figure where you will run the pipe, measure for pipe lengths and make a list of the fittings you will need. Any hardware store should be able to cut and thread the pipe for you and supply the fittings. Pipes and fittings need to be tight, but it is possible to overtighten, so don't use a 36" pipe wrench and put the muscle to it! When you get the valve in place, turn the gas back into the lines. Take liquid dishwashing soap and apply a liberal amount to each joint. Watch for bubbles. If there are any bubbles, you will have to disconnect the pipes back to that spot and redo them. Be very careful about cross threading pipes and fittings. If you do, that the pipe back and have the threads "chased" to clean them up. It probable would be easier to just replace an misthreaded fitting than to mess with retapping the threads. With reasonable care, you should have no problems. The gas and plumbing should be inspected before use.
