Cabelas offers a cheap option for musky rod. The tourney trail is $50 and comes in a 7'6" setup. They also have their predator line that is $130. Nice rod up to 9'. Or Shimano offers a Sojourn model up to 8' I believe that is priced similarly around $50.
The Abu reals are nice. If you go ambassadeur, I would avoid the cheaper lines. (S or SX). They have plastic internals and the gears blow out quickly. I had 3 friends buy the SX and the same thing happened to every single one. The C series would be a better option. I toss a Shimano Cardiff and have had no issues for 6 years with it. I believe its around $120.
As for baits, a lot of it depends on the waters you will be fishing. I've noticed different baits work better in different types of water with different types of forage. Local bait shops should have good options for the waters you will be fishing.
You can also look on the outdoors first site. They have a strictly musky forum and people give good info there and they also have a selling feed where you can get used baits for cheaper than new.

Not sure if I should plug their site here but if it helps you out then it was worth it.
A word of advise, be patient. Catching fish doesn't happen over night. It takes a lot of hours and a lot of focus to land fish. Don't throw in the towel right away. Stick with it.
Good luck
