Getting boarding pass for 2 separate flights

[mokuni]

Hi All,
I have a trip planned next year, that are purchased on 2 separate tickets:
1.) PER-KUL return Flying Batik Air Econ
2.)KUL-DOH-CMN return flying MAS/Qatar Biz (Booked on Qatar)

I'm not planning to leave Air side as its only a 4 hour layover in KUL.

-If I leave PER-KUL, how abouts do I get the boarding pass in KUL for my DOH--CMN leg? I'm assuming this is done at the Transfer desk in KUL?
-Also I'm actually planning to only carry backpacks so dont have luggage for this trip. However in the even I did have luggage, How would I have told the people from Perth, that I want my luggage to end up in CMN?
-Will assume the the recommendation on the above will be the exact same for the return journey.

Great if you can provide some advice on the above, thanks all!

Do Batik and MH operate from the same terminal at KL? If not can you get from one to the other without clearing immigration/Customs?

Re any checked luggage - being separate tickets will mean slim chance of bags being tagged through to CMN unless there is an agreement between the airlines concerned. If no agreement you'll have to collect the bags and head to check in. With a 4 hour layover that is a bit tight.
