Length of the title depends upon the type of submission you are doing. If you are doing social bookmarking, directory submission,etc. then you can keep your title short and if you are doing article submissions or press release submissions, then you have use title of appropriate length and it will be good if you use your keyword in the title of the article.
use your keyword during submission and change this across your all keyword . It will help you to incense your ranking in search engine
Keeping single keyword as title wont help, you need to keep long tail keyword. short tail title is sufficient for link submission, for article submission and social bookmarking long tail keywords such be taken.
It always advisable to include as many keywords as you can but make sure that Title tag describes your site the best and doesn't look like all the keywords are stuffed together.
