re: cav division fighting ability
They will fight better with 4 to 6 infantry in the division (and if it has infantry, it might as well have real artillery rather than HA), but for raids fighting ability may not be the most important consideration. The stack will move at the speed of infantry if even one infantry is in it, and the Hide and Evasion values go down too, so it depends on your goals for the raid. (If you have late-cav in it then a pure cav division will be able to capture enemy cities and their depots. Just something to keep in mind.) So, if speed, range and the ability to avoid combat (if you choose) are important, then all cav (and consider leaving the HA behind too, they are only medium stealthy) is a better choice. Even if you are just looking to range around the margins of the front lines hunting down small stacks being shuffled around (Athena usually has a lot of them) all cav with HA is probably a better choice than including infantry just because of the speed.
All Cav divisions will do fine in a combat if there is a Cav leader in the stack (he doesn't have to be in charge of the division itself to get the combat bonus) as long as you are careful not to get caught by too powerful of an enemy stack. The main benefits to having infantry in them come in the big Corps vs Corps sized battles: their speed and stealth properties are irrelevant in those situations, and if they get targeted you take all (expensive) cav hits. In that case the infantry act like cav-hit insurance, absorbing hits that would otherwise go to cav elements and improving assault phase performance somewhat. (For that matter, you might as well spread the cav out so there is some in each division of the Corps, but then it will be a chore to separate the cav from each division when you want them to break off from the stack to go do cav things.) Generally speaking, I would avoid combat with all-cav divisions unless I saw a good target of opportunity: combat performance considerations aside, cav hits are expensive to replace and the pool is limited.
OTOH, if you can afford 20,000 cav, and are willing to pay for (and have enough in the pool for) the replacements you will need, then they will probably do pretty well against anything that size or smaller, especially if Forrest is the Corps commander. Be on the lookout for weakly garrisoned depots and for smallish stacks that are not well-entrenched, have low quality troops or lack artillery; I imagine you would tear those guys up. Also, the further West you are on the map, the more viable cav stacks are for combat roles just because things are farther apart so speed is more important, and you are less likely to encounter strong opposition.
Let us know how you end up using them and how it goes. I don't have much experience raiding-in-force (its not something I usually do) and am interested in hearing more about how it works out.
(Clarification: when I say all-cav I mean Cav and Horse Artillery. They can be left behind behind for stealth missions, but otherwise there is no reason not to have HA.)
