Heya and welcome to the Tankers!
I've been mixing my own juice for a while, so here's some info.
Get some 30ml dropper bottles. Aromatherapy bottles are fine. These are to store your mixed juice once you find a flavour you like.
Which brings me to my second point. Don't mix huge quantities at first. The tanks are really good for this as you can do 1 tank-full and see how it tastes.
If you have an iPhone, there's a good mixing calculator on the appstore.
Otherwise, a good web one is:

Other kit that's useful.
10ml blunt-fill disposable syringe. These are good for picking up the flavour concentrate and also for tank filling without removing the end cap.
Blunt fill needles are available at :
BD Blunt Fill Needles 18G x 1.5 inch x 100 - MD305180 by: BD - at around £10 for 100 (!)
(I don't know if they'll ship to Malaysia, though)
Apart from that, you'll need Nicotine solution and a diluent - either Proylene-Glycol (PG) or Vegetable Glycerin (VG). or PEG-400.
The PG gives more throat hit, but less vapour, the VG is sweeter with more vapour and the PEG-400 give good vapour and throat hit but really likes brand new atomisers.
I also got some glassware because the nicotine solution tends to remove the markings off the disposable syringes.
I got a 10ml glass syringe, a 25ml measuring cylinder and a 50ml beaker, all from Ebay.
hope all this helps!
