So - to amend / correct my earlier posts...
All of the Nik modules can be used as individual standalone programs - however, it is only possible to load JPEG images if you use them in this way (however, you can save the resulting edited file as TIFF to prevent further compression losses).
You are better off using them as plug-ins for Lightroom and Photoshop (and possibly other compatible software) - in Lightroom, when using the "Edit In" function, a TIFF copy of the current file is created, and this is passed to whichever Nik module you are opening. When you finish editing and exit the module, the edited TIFF is passed back to Lightroom.
Since JPEG files are quite lossy and contain compression artefacts, it's better to use TIFF.

Maybe I'm realizing that PP isn't as clear cut as I hoped it to be.
unless I was to pay a good bit of $$$ I won't find a single software package to handle everything?
Darktable, GIMP, Nik Collection
Should I just consider buying Lightroom 6?
It's certainly possible to put together a suite of freeware to carry out decent post-processing, but personally I think it's worth investing in Lightroom 6 (it's what I use) - just be aware that it is an image library and development tool - and not an image editing tool, per se. Lightroom and Photoshop (or various editing plug-ins) work together to provide a full suite of functionality.
Another option to consider is Photoshop Elements 14, which includes Adobe CameraRaw to carry out pre-development of your RAW file before it loads into Elements. CameraRaw isn't quite as powerful as Lightroom 6 in terms of shadow and highlight recovery, but otherwise is pretty good for the basics of development, allowing you to carry out the major optimisation of exposure, colour and contrast etc. Elements is a good tool for general image editing, and if you don't want or need the library management capabilities of Lightroom, it might be a good option.
