3SGE (Gen3) Major service advice

Hi Guys
 
I'm very rapidly approaching my 200,000k service on my '94 SW20 Bathurst Edition MR2, running the standard Gen3 3SGE. Now while I do have a fair bit of mechanical aptitude, most of it has been built on Nissans, so I'm pretty new to the Toyota mantra and their way of life.
 
As far as servicing goes, I'll be tackling all the bigguns: Timing belt, spark plugs, all fluids, fuel filter, replacing water pump etc etc... I'll also be doing valve stem seals (blowing a bit of smoke under hard acceleration) and potentially looking at doing the head gasket as well just to freshen it up. 
 
My questions are as follows:
- I've had a look around and not finding any timing belt kits for the 3sge (inc. idler pulley/tensioner). I know Toyota share a lot of things, is there another one I can look at? 3SFE? 3SGTE? )Or shall I be chasing down all the parts I need individually?
- Is there anything you can recommend I also check while I have the engine out? (Not looking forward to dropping it and lifting the car over it by the way...)
- Car has had aircon fitted - Does anyone know if it's possible to disconnect the compressor from the engine block so I don't need to look at re-gassing?
 
Looking forward to whatever answers get thrown my way :) Thanks in advance

Iirc gen3 gte/ge share the same parts for all the bits your looking at. Maybe ge head gasket is thinner.

Just dont get any gen2 parts.

Many people to choose from for parts. Stick with genuine parts to avoid redoing your work.

Road and track, gorillas, gatesys, sq engineering and various nz toyota dealers can be cheap.

Be wary of getting from the US, not that they're bad. But it just ads a bit more difficulty as they never got the gen3 in any form iirc. So often their NAparts are for 5sfe etc. Its ok if you know what your doing. But can be confusing for new peeps.
