My birthday presents and setup help

[Fishnngolfn]

I went over my brother's house this weekend and his wife's mother asked me if I wanted any of her husband's old fishing stuff (he passed away a couple years ago). Of course I said yes. I don't plan on selling any of these so please don't ask. My sister-in-law's parents were like a second family to me when my parents moved up north.
One of her son's took the BIG bag of tackle but I got a small tackle box with about 10 cranks, 3 spinners, 3 Rattletraps, and some jigs. She also gave me 2 baitcasters and a spinning rod and reel. The only thing is the baitcasters are right-handed and I am a lefty when it comes to baitcasters. I am a quick learner though so again I am not selling them.

Baitcaster #1 - Quantom Pro 3c 6.2:1
Rod - 6.5' Mitchum Fulcrum F66MHT med heavy
interesting note: the thumb bar to let the line loose automatically locks back when I take my thumb off. I have to hold the thumb bar down the entire time until the lure hits the water

Baitcaster #2 - Diawa Procaster PM33P 5.1:1
Rod - 7.5' Abu Garcia Conolon Basslite heavy action flipping rod

Spinning Reel - Diawa 2505BL Regal-Z
Rod - 6.5' Browning Silaflex 915

All need to be cleaned up a bit. I am not familiar with any of these reels.
I would like some help as to determine what would be best suited for each rod/reel. Also what type of line should I put on each one with each type of fishing. With the addition of 3 extra rod and reels to my arsenal, I don't plan on changing out my setups, so each rod/reel will be for a specific type of fishing (weightless plastics, jigs, cranks, spinners, etc).

My other setups are:

Baitcaster - Abu Garcia SilverMax 6.2:1
Rod - 6.5' Berkley Lightening Rod medium

Spinning - Abu Garcia 5.2:1 Cardinal 302
Rod - 6' Berkley Cherrywood medium heavy

I am willing to purchase a new rod to go with any of these reels if it will improve the setup.
