If it helps we have a guide on our website for installing Sphax PureBDCraft for Tekkit Lite : http://themindcrafters.com/sphax-purebdcraft-for-tekkit-lite/ It has all the download links, step-by-step instructions, and a video how-to for installing sphax for tekkit lite (and other versions of the technic packs, too). Let us know if that helps!

We are starting to maintain something like what you're looking for. It's a massively manual process but if we do it once then everyone gets the benefit from it later - so we created a changelog page for 0.6.1 here: http://themindcrafters.com/2013/03/18/tekkit-lite-0-6-1-changelog/ I'm not sure what future formats of our list will look like - we might try and make it better to navigate than a 'post' type but for now that should help and we'll try and keep everything accurate and up-to-date as more releases come out. Hope this helps someone.
