If you tie good knots and use a leader you will find that 100# or 80# is overkill. Try 40# or if you must 60#, and if you rig it right you or the Muskie are not going to break it. And yes, bass lures will work well. My best Muskie was caught on a U2 Flatfish. But it is still fun to throw a big spinner or a monster surface plug. Your rod seems perfect for throwing big lures. You need backbone, but not a broomstick.
I always use a reel that is one or two sizes bigger than the recommended, as long as it has a large arbor or is a narrow spool reel. Those tiny reels for 2 to 4 or even 5 wt lines just take too long to crank in. For steelhead, bonefish, tarpon, or tuna etc. a drag can be important, but for most freshwater fish a good click and a palming rim is really all you need, and is more fun. I have taken wild browns up to 27" and a ten pound rainbow that way, and very few things beat the sound of that click buzzing. And for $25 go for the machined bar stock, although there is not much wrong with today's cast reels, as long as they are finished by machining. 76 years and still fishing. Have fun!
Good place to use them is right off the Ferris Wheel in downtown Seattle. The lights attract the squid. And, technically, this isn't snagging, because the squid come up to the jig and grab it, just like a bass taking a lure, except bass don't have eight arms and two tentacles.
You did very well. We lived in West Yellowstone for several years, and Lewis was my favorite spot, but in many trips I could not count not many in the five lb range. Congratulations.
Lewis Lake has lots of Brown Trout & Lake Trout, with perhaps some Brook trout and Cutthroat. While anything is possible, not likely to have any Rainbows.

Don't forget the Red Eye Wiggler in HUGE!
They are not snapper of any variety. They are either Yelloweye or Vermilion rockfish. If they have two ridges on top of the head above and slightly behind the eye they are Yelloweye, and Yelloweye are protected in Oregon waters. If they don't, they are Vermilion, or some other rockfish, and are OK.
If you run into a five foot pike I have to ask what country do you live in?
If you are willing to put in some practice a good revolving spool out fit will cast just as far as a spinning outfit. The energy it takes to get the spool rolling is offset by the line slap of a spinning reel. In truly expert hands the revolving spool (casting reel) probably wins. In respect to the level wind it will cost you some distance even if it is one that disengages on the cast. The level wind has the advantage for small fish trolling or bottom fishing from a boat, while most big fish trollers or long distance casters go without a level wind. If you will be catching fish that take out a lot of drag the revolving spool reel has the advantage of not twisting your line for every revolution against the drag. All that being said, if you don't have the time or inclination to really learn how to cast, you should probably just go with a good quality spinning outfit. Unless you are going for big sharks from shore. It that case, good luck!
Bobber stoppers on threaders. Put your line in the loop, pull it through.
Go with 2 or 4 LB line, and fill the spool. That's all you really need to do
