Hi Melinda!!
Congratulations on your engagement and wedding plans!
The ladies here are really helpful on lots of things, so go ahead and ask all sorts of questions, chances are, someone has the same thought.

We bought a planning book, its AMAZING! The Complete Wedding Planner and Organizer by Elizabeth and Alex Lluch; published by wedding solutions. They have done several wedding planners, so they pretty much have things covered and laid out in a logical order. Another helpful planning tool to make sure you catch everything is TheKnot.com, its free, its wonderful.

Ask friends and family that have recently gotten married what their biggest mistakes was, who the best area vendors are, etc. Remember: asking for advice is not forcing you to take their advice. But they have just gone through the same process, they may have some tips.

As for your green color.... I don't know, we are taking our fabric swatches to a paint store to get a better name (and the exact color mixture). Many paint stores are now "able" to scan your color into their computer and duplicate it in paint or at least the print out of the info for a small fee. Even just comparing your color to the available free paint chips.
