I have a 27 inch, late 2009, 3.06 GHz Intel Core 2 Duo with 8 GB 1067 MHz DDR3, and would like to increase memory to 16GB. Is there any problem with doing so? And how do I know if the memory chips I want to buy are compatible?
Thanks.

Yup, just found it myself and was going to delete my question. Thanks for the help. Though it's always nice when folks realize some of us just aren't as savvy as they are and respond with kindness. Just sayin'.

Yes, you can - as long as it is a late 2009; check this page (and find your model identifier:

If you have 2 x 4 GB now, all you need is to add another matching 2 x 4 GB. If, however, you have 4 x 2 GB, you have two choices: take out one pair and put in 2 x 4 GB for a total of 12 GB (that's what I did) or remove all four and buy 4 x 4 GB - your choice. Make sure you match the RAM horizontally.
Thanks so much!
I've been having issues with "Not enough memory to complete requested action" messages. When I work I have a lot of applications and files open at the same time. I've kept my Activity Monitor running, and the memory drops pretty low--below 1 GB--on a regular basis. I need all that open to do my work, so I'm hoping increasing the memory will eliminate that issue.
Both Lion and Mountain Lion are memory hogs, so - if feasible - you can mitigate a bit by quitting applications you don't need while doing some memory intensive task with another application.

There's a "Report post" link for alerting the hosts if you feel you've been treated with rudeness...
