You don't need 1.2 to play the later patches.
To be specific, if you only have RTW, you only need the 1.3 and 1.5 patches. Forget about earlier patches. Just those two.
If you have BI on the other hand, alongside RTW, I think I am correct in assuming that you only need download the 1.6 patch (it auto-patches RTW 1.3 to 1.5 - or should). Just by installing BI it autopatches RTW to 1.3. BI is classed as 1.4.
Hope that helps.
