Agree, how many at a time and what you are trying to accomplish makes all the difference.
The reason so many pros and active amateurs use Lightroom is the ease of importing, selecting, editing and setting up for use now or later .. Develop, Print, Slideshow or Web..
Most important is that you get ALL your photos in ONE File with the structure of the sub-folders whatever works best for you. by dates id popular, by events, by shoots. lots of ways. Can be pretty much wherever you want. I use iMacHD>user>Pictures>EBLPhotos. After setting that up on the hard Drive I import from the card using LR to hat ever folder I select or a new one. Once in LR catalog I again sort or delete.
The first thing I do is crop and straighten, then check white balance, look at histogram for blow outs and then basic editing, tone curve, and Details or vignetting. The options are numerous and can be very close to Photoshop although that, or Elements, is where the last "polish" is applied.
You can also use Photoshop Elements with the organizer to accomplish a lot of that .. at a much more reasonable price. With the Organizer and Adobe Camera Raw a lot is accomplished prior to the fine tune in the Editor.. PSE 9 has been on sale recently. Check adobe.com/products
Suggest a book on "Digital Photography" of which there are many and sort of follow through the author's suggestions.
Google any question you think of and be surprised at the result.
Enjoy ... that's what it is all about,
