    Well, I'm ordering the T420 with stock RAM and upgrading myself. Problem is I don't know which type to get? There's different speeds and different pins like 200-pin.

    I just don't know which type of RAM is compatible with the T420. Anyone can shed some light on this is greatly appreciated! :D

    I suppose you order 2GB RAM with your CTO and want to add another stick of 2GB to make 4GB total. Or, if you really need it, you can get a pair of 4GB and boost your notebook to 8GB total.

    RAM type: 204-Pin DDR3 SO-DIMM DDR3 1333 (PC3 10600).

    As stated above, any DDR3, max 8 GB (2 x 4 GB sticks). Dual core i5/i7 will support 1333, quad core i7 1600.

    DDR3 1333 (PC3 10600)
    DDR3 1333 (PC3 10660)
    DDR3 1333 (PC3 10666)
    All of these will do, correct?
    Newegg

    I'm planning to buy one of these, Corsair 4GB or this GSKill 4GB

    Yep, that's just naming inconsistency, with some manufacturers terming it 10600 and others terming it either 10660 or 10666. I recommend the GSkill stick, since it's cheapest--go for the lowest price with the same specs, the manufacturer really doesn't matter when it comes to RAM.

    Don't bother with brand name RAM. Get whatever's cheapest. Either it does the spec. or it doesn't.

    I've been very happy with G.Skill RAM. Reliable, and reasonably priced. I use it on a number of systems, and so far I haven't had a failure.

    Yes.

    Again, brand does not matter. At all. Ever. For any RAM. The only thing that different brands of RAM offer are different labels. Ostensibly some brands have different QC than others, but that doesn't really matter; this isn't like hard drives where QC affects the lifespan of the product -- either the RAM works and passes memtest, in which case you keep it, or it doesn't, in which case you take advantage of NewEgg's return policy.
