IPhoto hangs, found Console message

Question

Though I'm a Mac user for over 10 years, I'm no good when deciphering Console jargon or attempting a Terminal command.  My iPhoto has (as well as most everything else with Mavericks) been unusually slow when opening, importing, changing folders, editing, tagging, opening a slideshow, etc...pretty much in every way.
I opened Console as advised and found this repeated message (happening 4-5 times per second) while I was either opening iPhoto or importing 3 photos:
11/12/13 8:47:57.000 AM kernel[0]: Sandbox: mdworker(3284) deny file-read-data /Users/jchadwickwilliams/Pictures/iPhoto Library/Contents/PkgInfo
11/12/13 8:47:57.000 AM kernel[0]: Sandbox: mdworker(3284) deny file-read-data /Users/jchadwickwilliams/Pictures/iPhoto Library/Contents/PkgInfo
the final line of text that stopped this repeated text was:
11/12/13 8:48:31.961 AM WindowServer[125]: disable_update_timeout: UI updates were forcibly disabled by application "iPhoto" for over 1.00 seconds. Server has re-enabled them.
Any ideas what any of this means?  I'm really at a loss with this data...looks like something in my iPhoto library is invalid?
I know this next question shouldn't be in the iPhoto section, but perhaps it is related somehow. 
I don't recall what I was doing at the time, but one minute prior to the iPhoto messages, I noted these messages alternatiing over 60 times:

It seems I've got some major issues.  A point in the right direction would be GREATLY appreciated.
Thanks,

OOOKKKAAAY, I exported a slideshow this afternoon (about 800 photos) and as has been the case for a couple years, it took forever....the second half of the exoprt had no preview screen, just a black box.  It must have taken 2 hours.
I just looked at Console and found a MOUNTAIN of errors.  One thing I noticed about the exported slideshow is that some of my preferences for individual slides were not maintained and the show went on as if I didn't edit/alter the overall theme of the slideshow.  I went back and personalized each slide setting again to find they sometimes worked in preview mode, but then when I returned, my preference for the slides were missing.  FRUSTRATING.  And so are those obscenely replicating Console messges...I'll throw out a few that have taken over my screen real estate:

I'm getting denied a lot on my own system.  And it seems my system doesn't have sufficient ability to handle the workload as I see I'm using, "too many resources after 2048 files". 
I think I'm going to try to rebuild my entire database.  What have I got to lose?  iPhoto worked FAR BETTER as a guest user.  Does htis mean I should toss my plist files? 
And as always...computer connoisseurs, child prodigies, insightful sages, and holy healers are all encouraged to respond (as is anyone else with mindful advice, I'm not that picky).
Thanks for throwing me a life-line,
