The amount of trans slots something gets depends on the grade of the item. Armour gets 2 sockets in general (crafted/onyx etc.), with heroic SD armour being the exception, 1 slot
For weapons it goes as follows:
- Glacial = 2 slots
- Onyx = 3 slots
You Always need a shiny trans stone to trans an item, no matter which item you trans.
Also wizzard is a sh1t class, drop it. If you want a cheap class to farm with, make a full INT dekan sage. They are cheap to make, maintain and have really good defense and attack. Another option would be to make a full AGI predator, althrough katars are the most expensive weapons.
