And are quantum reels and rods good? I am showing pigs at my fall fair and will auction one off, most pigs go from anywhere between 300 and 500 dollars and am looking to get a nice rod and reel with the money.

I will dive in on the Quantum reels since they are the primary reels that I fish begining with the later series of PTi-B spinning reels and the newer series of casting rods. I fish the quantum reels I have which include the Catalyst A&B, and Kinetic spinning reels and I also have the Energy, Kinetic and Accurist casting models and Never have had a problem out of them. I fish 4-5 days out of the week from spring through fall here in chicago and my reels have held up with regular cleanings in the off season for years without a problem. I know others will recommend Shimano or say the Quantum products aren't good but that is not the case for me. They are my First choice in reels for both spinning and casting followed by Daiwa.

Whats the difference in hieght in a rod?

Length plays many parts, from shorter rods for greater casting accuracy and leverage to longer rods which offer greater casting distance and more power. There are no hard and fast rules in terms of what one rod length will or will not do, it's based very much on manufacturer. Along with length, you also get into action and power when choosing a rod.

In bait casters how do more or less ball bearings make a difference?

Bearing count isn't everything in a reel. In very general terms it most typically equates to how smooth and efficient the reel performs. That is a very general answer, without going into great detail of what other factors you look at instead of just the bearing count. As a point of reference a 7 bearing reel that has bearings in the right place and is machined to tighter tolerances will always perform better than a reel with 10 bearings that has lower tolerances and less rigorous quality control.

What is the difference in the series like the Guide series and Reaction series and such?

Which "Guide" series of rod? There's not really enough information in that question to answer the full two parts. There are a lot of differences in the series of rods. A Reaction series rod is a rod that is made specifically for moving baits and treble hook lures. It has a, generally, softer tip and more progressive action through the length of the blank. It is designed to protect the hooks on moving baits from the fish throwing them. There are many differences that can be discussed at great length when it comes to this question.
