New user from corel, workflow advice needed

Hi I am a professional new to cc,

For years I have used a combination of Corel draw suite and acdsee.

Corel was fantastic for vector images and photopaint is very easy to use.

Now fed up of exporting my work to Adobe formats for clients as I am the only person in advertising not using them i have finally changed to Adobe CC.

The core programs photoshop and illustrator are obvious and i can navigate my way in them. My problem is image management and batch processing photos and drawings.

I used ACdsee for this, it enabled me to view folders and thumbnails and to do basic editing on the run (cropping, colour balancing)

The most the useful, Batch renaming , batch resizing or batch converting file formats.

ACdsee has become less useful as it has become bloated trying to do too many things so its speed has suffered

I was hoping that Bridge or Lightroom would replace acdsee  but I am confused about their function.

Lightroom seems to be only useful for photographs and has limited batch capabilities , Bridge depends on opening photoshop and seems to have little use other than a file explorer or library.

I know that I must be missing something obvious. With this huge powerful suite is it still necessary to have irfnview or acdsee?
