As far as losing your centerstand you will have to contact each of the headers manufacturers you are considering for that question.
Slip ons should not require rejetting, but going to a full system will definitely have to do be done as well as filters usually. If you just want a better rideable bike go with a Stage 1 kit.
If you are serious about getting your bike lighter, you will want to look for magnesium. titanium and carbon fiber parts, but IMHO you will not find a lot for your bike out there.
One of the most expensive, but well worth mods on any high end bike is going to Carbon Fiber rims as you will lose lots of rotational weight from the bike.
My suggestion is to go with a Stage 1 kit and work on upgrading your suspension to make it a better ride. You can look into getting progressive springs for your front forks. Try works performance products. www.worksperformance.com , race - tech or progressive springs.
