Watch for evidence of flair, and try to make sure the light is even.
Do yourself a favor and try LODIMA paper and follow Michael A. Smith's advice on development. You will never see a better silver print.
Any book on photography printed prior to about 1980 will provide good concise instructions and information about materials.
A point to remember - Enlarging paper are many times faster than contact papers and very quickly overexposed with an ordinary light bulb. A 7 1/2 watt bulb at 4 feet covered with several layers of toilet tissue provides plenty of light for enlarging papers.
I realise that availability might be a problem over in USA, but Foma make a perfectly adequate (even rather nice actually) contact-speed, silver-chloride, double-weight paper. The name of the product is Fomalux and is available, in Europe at least, in a wide range of sizes.
Fomalux can help in the process of making a contact-print as it is a lot slower than normal enlarging paper, ISO-P 12 versus ISO-P 110 for the equivalent Ilford Galerie paper, making the traditional hanging light-bulb printing method more practical and has a very 'traditional' appearance. It is a fibre-based paper, rather than RC, so if the OP can obtain some of the paper, he might also want to find some washaid to make the washing more quick and efficient.
Just as a point of information, it used to be possible to obtain Fomalux in RC, though hard to track down (I got some through the good offices of an APUG member from the Czech Republic); it doesn't appear on Foma's website, so perhaps they have stopped making it
I am now sure for which reasons you want to do a contact print; is it for proofing your negatives or just getting an overview of your images? If your main goal is proofing, check out the link provided at the end of this post.
As Mr. Halfhill writes in his article, you should expose your paper until your blacks are black, not less and not more. You do test strips to not to find a workable exposure for most of your negatives, but to find out when the most transparent part of your negative (the "whitest" part) becomes black on your print.
If you "standardize" your process this way, all of your proof sheets can be compared. Plus, you get some information as to whether you will need to burn or dodge your print excessively, or whether all tones of gray will simply pop out of the developer.
