I would suggest not trying to learn two software packages at once. Stick to Lightroom and when you have that down, then add other software to your repertoire.
We have a whole set of Lightroom tutorials
HERE that guide you from the very basics right through to advanced editing. Learn and then the
workflow that suits you will follow. There is not 'correct'
workflow, you develop yours as you develop your skills, based on what works for you.
Trying to learn a heap of different software packages at once is just going to slow your learning process down.
Mine is:
Import photos from
memory card into lightroom, tag them with keywords and import to relevant folder on hard disk
Open images one by one in Library module and use the X key to reject any I don't want
Delete rejected photos
Go to develop module and do 'whole of image editing'. Straighten horizons, adjust white balance, etc
Move photo to Photoshop
Edit as I see fit
Add watermark
Sharpen
Save
