What is the difference between a cer, pvk, and pfx file? Also, which files do I keep and which am I expected to give to my counter-parties?

Windows uses .cer extension for an X.509 certificate. These can be in "binary" (ASN.1 DER), or it can be encoded with Base-64 and have a header and footer applied (PEM); Windows will recognize either. To verify the integrity of a certificate, you have to check its signature using the issuer's public key... which is, in turn, another certificate.
Windows uses .pfx for a PKCS #12 file. This file can contain a variety of cryptographic information, including certificates, certificate chains, root authority certificates, and private keys. Its contents can be cryptographically protected (with passwords) to keep private keys private and preserve the integrity of root certificates.
Windows uses .pvk for a private key file.
I'm not sure what standard (if any) Windows follows for these. Hopefully they are PKCS #8 encoded keys.Emmanuel Bourg reports that these are a proprietary format. Some documentation is available.You should never disclose your private key. These are contained in .pfx and .pvk files.
Generally, you only exchange your certificate (.cer) and the certificates of any intermediate issuers (i.e., the certificates of all of your CAs, except the root CA) with other parties.
In Windows platform, these file types are used for certificate information. Normally used for SSL certificate and Public Key Infrastructure (X.509).

I actually came across something like this not too long ago... check it out over on msdn (see the first answer)

I summarized the info from the page based on the suggestion from the comments.
Here are my personal, super-condensed notes, as far as this subject pertains to me currently, for anyone who's interested:
