Actually, Tom Baker was the fourth Doctor. Jon Pertwee was the third.
Here's a
Beginner\'s Guide to Doctor Who , starting from the Classic era. Unfortunately, it only seems to offer photos and no text - there used to be a better guide on the BBC site. :p
For those with a bit more patience, the
Episode Guide for the First to Eighth Doctors offers photos of each Doctor, a list of episodes (they were all four or six-episode serials in those days) each Doctor was in, and also a guide to companions.
Traditionally, by the way, the Doctor was supposed to be asexual - never stated, but there was never any overt 'shippiness' between Doctors and companions (though it came close between Four and Romana II - it didn't hurt that Tom Baker and Lalla Ward dated and then got married while the two of them were playing those roles
). The 'asexuality' all changed with the Eighth Doctor, who kissed his sort-of companion, Grace Holloway, at least twice; and while the Ninth and Tenth Doctor and Rose's romance is not much more than subtext the writers and actors are all on record as saying that
it's a love story and - as David Tennant has put it -
They're boyfriend and girlfriend without the shagging.
You can also take a look at
Wikipedia , which is stuffed full of DW information.
But you're probably better asking specific questions, because otherwise you'll drown in the amount of information you'll get!
