Your best option is to read the light novels of 'Toaru Majutsu no Index' first, if you want to grasp the entire concept. Other than that 'Toaru Kagaku no Railgun' takes place before the events of the 'INDEX Timeline'.

The light novels give more accurate story of the 'TOARU Universe'. 'Manga' and 'Anime' will have much of the facts cut up in a short format. Also the 'PSP' games of the 'TOARU Series' also have plots occuring in between the timelines.

So... it's your choice.

Want a fast hand's down information... Then watch the 'Anime Episodes'.

Want additional content... Then read the 'Manga Volumes'.

Want entire descriptions with secret cutscenes... Then the 'Light Novels' is your choice.

Personally speaking it's best to watch the 'Anime Episodes' first and foremost before diving into this particular Universe.
