We've all been there!

Lightroom is one of the best catalogue management and RAW development tools available... some would say *the* best, while some prefer other similar applications, but they all have a fair learning curve.
I'd advise against trying to learn too many things at once, as it's all too easy to become overwhelmed. Right now, the K-70 is more than enough for you to be getting on with, so I would suggest that - for now - you maybe shoot JPEG (or RAW+ so that you have RAW and JPEG versions of your files). That way, you can enjoy the photos you're taking straight out of the camera, without having to rely on post-processing.
Once you've got the hang of your camera - at least, enough to handle typical shooting situations, and to find your way around all of the features and menus - then perhaps concentrate on learning Lightroom. There are some excellent books on the subject - my favourite, recommended to me by another member here, is
"The Adobe Photoshop Lightroom CC / Lightroom 6 Book: The Complete Guide for Photographers" by Martin Evening. It will take you a while to work through it, but by the end you'll be able to organise your catalogue of images and process them with a high degree of proficiency.
