How Should I Begin Studying Topological Quantum Field Theory?

[FedEx]

Hello,

Can anyone tell me how to go about studying Topological QFT. I am fine with QFT, Fibre bundles and currently doing Cohomology from Nakahara. Should i directly start with Witten's paper or are there any more elementary review papers?

Thanks.

In case you haven't seen them, these seem to be pedagogically oriented:
