Here are some links that we have found particularly useful. This is not meant to be exhaustive, but it is a good start. 
Find below: Resources to help with papers, info on postgraduate philosophy options, more philosophy talks in St Andrews, and more.

Some of this links require an Athens login. You can pick one of these up at the University Library.

The Overview Resources

These three provide a solid grounding on almost any topic, without you having to read the papers. Sounds fantastic, but you should be aware some are really rather bias. There is no substitute for reading the paper first hand.

Stanford Encyclopaedia of Philosophy: Almost every philosophical topic covered (mostly) by leading scholars in their field. It can get tricky, it can be biased, but it can be a tutorial life-saver. It shouldn't replace speaking to your tutor, but it is a brilliant resource. 

Routledge Encyclopaedia: Requires and Athens account (see above). This is similar to the SEP above, and covers many of the same topics. It's often more accessible than the SEP, so reading both entries is a good start to any topic.

Internet Encyclopaedia of Philosophy: Again similar to the two links above, but this boasts peer-reviewed articles. Take a look at all three and pick you favourite. 

Writing Philosophy:

Jim Pryor Guide: This is not substitute for going to your tutor's office hour, but many in the department recommend this no-nonsense guide to writing a clear and concise analytic philosophy paper.

Philosophy Talks around St Andrews:

Philosophy Club: Meets 5 or 6 Wednesdays a semester in Edgecliffe at 4:15. Check for regular updates about the speakers.

Where To Find a Paper: Generally just whack the search into GoogleScholar . What you are looking for will usually pop up. Be aware however you wont necessarily have access to the link GS supplies. Try looking elsewhere, such as the links below.

Jstor: A simple search engine of online Journals. Try to limit what you're searching to just Philosophy, otherwise you  risk getting lots 
of unsuitable stuff. (You will need Athens to get the whole downloadable PDF.)

PhilPapers: A bit more general than Jstor, you can simply browse by topic area (i.e. epistemology, metaphysics etc). A good resource if Jstor turns nothing up.

Also don't forget that the library has access to many e-books. Some of which may contain the specific papers you're looking for.

(Gutenberg Etext does a similar job.) 

Further Study of Philosophy:

Philosophical Gourmet A guide to philosophy departments around the world aimed at those considering postgraduate work.  This is somewhat controversial, so we recommend a Google search to help you decide how much to value the results of this.
Applying for Graduate Work A concise guide to applying to do a postgraduate degree (here’s the US version.)
Philosophy Departments Around the Country Information on and links to the British philosophy departments.

The Moral Maze Discussions of the moral aspects of current events.
"In Our Time" Philosophy Section Radio 4’s programme on intellectual history.  Always a good listen
The Reith Lectures The fascinating annual lecture series is available to listen to online from the BBC
Beyond Belief 2006 Footage of the entire two-and-a-half day conference held in November 2006 by a group composed mainly of scientists, but with some other thinkers, including philosophers, to discuss issues around science and religion. Perhaps not enormously balanced, but stimulating nonetheless.

Other stuff:
Philosophy Now Magazine One of the few extant philosophy magazines. Occasionally interesting, but nothing special.
Prospect Magazine Very interesting popular journal of ideas.
