You might want to try "Jackson's Valley Campaign, The Battle of McDowell" by Richard L. Armstrong (1990, H.E. Howard, Inc.). This 122 page book, a part of the Virginia Battles Series has about 7 maps of the campaign and battle. The index lists several entries for: Hyman's Battery, Battery K & I 1st Arty., Battery G 12TH Independent Battery and the 25th, 32nd, 55th, 73rd, 75th and 82nd Ohio Infantry. As I remember, there is an issue of "Blue and Gray" Magazine devoted to this battle as well with many maps down to regiment, etc.
