Well,
You didn't mention whether you will be using fly or spinning gear. Oh well, no matter, I think the choice of what to use is pretty simple - flies, usually dry but a few beadheads thrown in for variety, and small. Small meaning sizes 18 on down. Griffith's Gnats, Mosquitos, Black Gnats, Sierra Bright Dots, Royal Coachman, Elk Hair Caddis, and for nymphs/larva good ol' Hares Ears, and Zebra Nymphs should round out an ample supply.
If you're using fly gear, a floating line (I use a 4wt, 9' or my 1wt, 7' rod for everything), couple of 6x and 7x tappered leaders (I like RIO), a couple of spools of leader material, some floatant, forceps, that's about it.
If you've got spinning gear then a fly & clear bubble setup is the way to go. 2lb test is plenty and you may want to bring along some smaller leader material to connect to the fly. Don't forget the floatant.
Most of the fish want the flies high and dry - most of the time. I've done better in the afternoons on nymphs retrieved SLOWLY on the lakes but the majority of your time on the water should be early am just before and just after the sun starts to warm things up. Otherwise just at sunset when the mosquitoes start to get annoying
. If you are on the water at the right time and fish are rising but not to your fly then go smaller and/or dry the fly out and re-treat it with floatant to get it floating high. Sometimes the fish want a size that is very difficult or impossible to see so it's sometimes a compromise between getting more takes and being able to see the takes.
Lone Pine Lake should be your best choice. I haven't fished Mirror but it looks promising. Oh, don't forget to give the pond at the Portal a try! It isn't very "sporting" but it sure can be alot of fun and the fish were delicious.
