I'd be happy to help. I'm afraid I know very little about modding in and of itself, but where I can help is creating the text descriptions for a Trek style tech tree.
For instance, one of the advanced knowledge segments might be:
Tree Title (V'ger Download) +10 Research
In 1996 The Earth probe Voyager was launched in an effort for its creators to learn more about its solar system. It, like many such efforts from various civilizations, eventually left its solar system for parts unknown.
Now, centuries later, and thanks to an incredibly advanced (but now extinct) race of living machines who gave Voyager the means to complete its mission to, "Learn all that is learnable." it has returned with knowledge that spans the universe.
With so much knowledge in fact, that it had become sentient and wandered the universe seeking purpose. Our scientists attempted to intercept it and access its vast knowledge. Somehow the machine merged with the chief scientist and both disapperaed.
However, the scientist was able to begin the data download before man and machine began to merge. In that nanosecond we recieved terabytes of data that will take our scientists years to fully comprehend. However, there are elements that we can apply immediately to greatly improve our existing research abilities.

If this has any appeal to you I'd have to know how many spaces each part of your new tech tree (if there even IS one) would have.
