Those kits are called Death Kits in the ac community. Go over to the ac board and ask about the kits. They will tell you this:
Stop what you are doing. Don't run the ac. Take your car to an ac specialist. Have the system evacuated, flushed, vacuumed and recharged.
The most significant problem with the death kits has not appeared (from what I see here) to effect the 9000. Unlike a lot of other cars, even the older 9000's appear to use a desicant in the receiver/drier that is compatible with r134a. Most cars with r12 systems had a form of charcoal in the receiver/drier or accumulator. The r134a causes the charcoal to breakdown and escape into the system, and then pretty much destroy everything.
There are 2 remaining problems with death kits and the 9000. First, is the lack of flush. You really do need to flush the system to get the mineral oil and other crud out. The second is air in the system. Since you did not have a vacuum in the system to charge into, there is certainly air in your system. The air will reduce efficiency and will cause excessive high side pressures that will eventually kill the compressor. Also, you put too much ester oil into the system which reduces heat exchange in the evaporator.
This is what I would do in your shoes: Make a choice. Do you want to invest the time and money to educate and equip yourself to work with auto ac, or do you want to pay someone else to do it. If you want to do it yourself, you need a manifold gauge set, a garden weed sprayer and a vacuum pump. And a book on auto ac (Haynes makes one that is almost ok). The total equipment cost is probably less than $500. The education you can get here and on the ac board.
You have a Sanden SD709 compressor, replacements for which I hear are hard to find. A rebuilt unit is at least $220 on the internet and probably more. I don't think new ones are available. When the compressor is replaced, you will also need to have the system flushed and replace the drier. The ac shop will probably refuse to install a compressor you provide and will find a more expensive alternative.
What I am trying to say is that if you don't want to get involved with auto ac (and there are many good reasons not to), then take your car to an ac shop and have them fix what you have done. It will probably only cost around $100-$150. Because, otherwise, you are likely to be paying them ten times more in the future when they replace your compressor.
Someone should really bring a class action suit on those kits. You just can't get an ac mechanic in a $30 box at Walmart. The words on the box are totally misleading and the instructions are lies.
