Should i use my computer docked Nvidia GeForce 9400 GPU to mine LTC?

What's the easiest/best way to join an LTC mining pool?   How much LTC will i receive a day?

You will be hashing really slow probably less than 10 Kh/s. Not worth it really. Do you have any other card to use? With that card you will probably get:
0.02 LTC / Day
0.5 LTC / Month
6.1 LTC / Year

Unfortunately i don't have another card.  I think i'll just investigate the prospect of buying into outfits like Cloudhashing, ASICminer, Avalon and so forth rather than wear out my computer over 6 LTC a year.  Thank you for the helpful info.
