all the page titles  in my site have hyphens between the words like this: http://texas.com/texas-plumbers.html

I have seen tests where hyphenated domain names ranked lower than non hyphenated domain names.  Does this mean my pages are being penalized for hyphens or is this only in the domain that it is penalized?

If I create new pages should I not use hyphens in the page titles when there are two or more words in the title?

If I changed all my page titles to eliminate the hyphens, I would lose all my rankings correct?  My site is 12 years old and if I changed all these titles I'm guessing that each page would be thrown in the google sandbox for several months, is this true?

Thanks mozzers!

what is the best tool for finding what people are using as search phrases for my product?  i used to use the google adwords keyword suggestion tool but that tool is gone now.  Is the google keyword planner now the best tool to use?

Thanks,

what seo benefit does setting up a photo gallery where each photo is a separate web page?  My old SEO guy set up my photo gallery like that claiming that because each photo was a separate page, it added a big seo benefit and i never understood what he was talking about.  Maybe alt text on the photo with key phrases in it pointing to my other pages to give my site a theme for google?  I'm not really sure.   He has since moved away and i am considering redoing the photo gallery to multiple images on one page to be more user friendly to my users.  This photo gallery is 3 years old and the photos might have some page rank to them helping my site so i don't want to remove this gallery if there really is a benefit to it and it will hurt my site.  I once removed four static page rank 3 pages from my site that weren't used for my site anymore and my rankings dropped 5 positions.  Thoughts anyone?

Thanks!

i only have about 4 reciprocal links, the rest are one way.  I left these reciprocal links up because there is good anchor text in the incoming anchor text.  Does google penalize my site by a small amount if the site i'm linking to links to a casino site?
