1992 Acura Integra home do it yourself kit retrofit to R134

I want to use a do it yourself kit to recharge my a/c unit which is dead, to change it from R12 to R134 and since it has such high mileage I want to do it myself. The compressor is fine, the a/c is empty (no cold air at all) I've do this on another import and it worked great-just wanted a expert opinion on not vaccuming out the old R12 and retro fitting the conections myself-along with adding the R134 with lubricant cans by myself to get the a/c unit up and running again - it takes 34oz or a little less than 2 lbs of gas. Thanks in advance for any tips-Z
