disregard the thing at the bottom where it says you can have a spray 92x92 that doesnt work cause its not a power of 2 or something.
also if you want to make a spray with an invisible background i found this sight helpful:

you dont have to do all that drop shadow crap, if you dont want a drop shadow just skip it.
for tga stuff you should use irfanview, it works with tga files and it can do batch conversions and renames so you dont have to do them manualy
