Is PS Lightroom 4 just a way to process and cataloge photos. I notice that there is no save to option button only an export option. Does this mean that once the images are processed they are to be exported to a editing program to save?

Essentially that's correct.  The adjustments you make are actually saved in a separate file; if you want to create a copy of the photo with the adjustments applied you export it to another file and you choose what type of file that is, as well as making other choices during the export such as resizing and compression rate.

I export to another folder within the same folder where the original resides so it's easy to find.  How I export depends on how it is to be used.  I export a small jpg for Facebook, whereas I'll export a full-size version for printing from Qimage.  If I'm exporting for further editing in PS, I'll export a tiff.  If I'm going to Photomatix for HDR processing, I use the plug-in so an intermediate file isn't necessary.

Lightroom is a "non-destructive editor".  That is does not make any changes to the image file itself, it only saves details of the edits that you wish to make in its catalog (database).  These edit details are saved automatically as you make them.  If you want to "undo" or alter one of the edits, you can do this at any time in the future.

If you need to use an image file in a different application, e.g. to post to the web, to attach to an e-mail, to print in an external print program or to carry out more advanced editing in something like PSE or CS6, then you can create a new file with all the current edits applied by "Exporting" the file from Lightroom.  The "Export" can be a JPEG, TIFF or PSD file.  (I normally delete these files when I have used since since I can always "re-export" them in the future if I need them again.)

If you are just reviewing the files on the screen in LR or printing them from LR there is no need to create a new file with the edits applied.  The edits are always applied to the on-screen image and a temporary edited image file will be created when you print from LR.

You can save a particular edit state within LR by creating a "snapshot" or "virtual image".  Snapshots are useful if you want to get back to a particular edit state.  Virtual images are useful if you want to work on two different versions of the same image at the same time, e.g. one in colour and the other in B&W.

I hope that this helps.  The non-destructive editing workflow is a little difficult to understand if you are only used to PhotoShop workflow.  It has the enormous advantage that you only have to permanently save your original image files and the LT catalog.  You don't finish up with multiple versions of the same image file as you tend to do when when using PhotoShop.

No it doesn't.

Lightroom is pretty brilliant. It stores and organises your pictures and allows a great variety of different ways of classing them by your assessment, tags, metadata etc. You can create collections, sets of collections and smart collections which search your entire catalogue of shots.

Any editing work you do is non-destructive: that is Lightroom stores the original image and stores in a database the changes you made, so when you view or print its the shot plus changes that you see. If you export it also carries the changes: BUT here's the genius because the editing is non-destructive its very easy to make a virtual copy of your image inside Lightroom and treat it an entirely different way and because of the way the programme remembers the work you did - ie as data not a copy image - it doesn't take twice the disk space, and you don't have to keep track of renaming copies etc.

Personally I think Lightroom is a great programme its very photographic rather than having the graphic emphasis of programmes like photoshop.

Also right now its price is a bargain

Does Lightroom support tagging like name tags that are saved to exif data? This is one new feature of Picasa 3.9 that I've really started to like. Name tags are not just saved to the Picasa database but it actually added to one of the exif fields. So now I'll never forget who the people in photos are.

Yes, LR writes tags (called keywords in LR) to the relevant EXIF field (it might actually be an IPTC field) when a file is "exported".  You can also export the tags with raw files.
