Hmm, well I used to have wiki access, at least for the FF9 section.
Abit of expansion of your savemap info:
$602E-$6030: Gil
$603B: Number of characters in party
$603C-$6042: Character indices/slots
$6043-$6049: Levels
$604A-$6050: Low byte of current HP
$6051-$6057: High byte of current HP
$6058-$605E: Equipped headgear
$605F-$6065: Equipped armour
$6066-$606C: Equipped bracers
$606D-$6073: Equipped accessory
$6074-$607A: Equipped weapon
$607B-$6081: Equipped materia
$60C1-$60C7: Low byte of max HP
$60C8-$60CE: High byte of max HP
All the data from levels to max HP are stored in an array of seven bytes, one by for each character (so for level, $6043 for Cloud, $6044 for Barret etc..).
Also, in bank 0 @$D4F8 ($54F8 in the ROM), there's 56 bytes which contains the initial stats of all seven characters (with 8 bytes each), it's stored like this:
byte Level
byte Headgear
byte Armour
byte Bracers
byte Accessory
byte Weapon
byte Materia
byte Materia Level
