CS6 Pshop - Alerts at startup; "All Readable Documents" not defaulting at opening; Format in file name not same as Format list when saving file

Question

Just downloaded CS6 Design Standard. System - OS10.6.8 (about to upgrade to 10.8), iMac 27 i5Intel 4core 12GBram 2.66Ghz
As Pshop opens, I get three alerts...
1 - Could not load Enable Async I/O module because does not work with this version of Photoshop
2 - Could not load Multiprocessor Support module because does not work with this version of Photoshop
3 - Could not load FastCore Routines module because does not work with this version of Photoshop
Then asks if I want to be connected to internet or something like that. Then Pshop opens even before I click OK
None of these happened with CS5.5
I realize CS6 is 64bit. I have CS5.5 set at 32bit because of plugins.
Two issues I've noticed so far with CS6.
1 - As I open a document, the Enable selections drop down at bottom of window is not set on anything. I have to always select the All Readable Documents. Not the case in CS5.5 which was always default at All Readable Documents. Could not find anything in Prefs to this issue.
2 - When saving a document, whether RGB or CMYK, the drop down Format selections are not accurate. The first three or four do read correctly as correlating with the suffix (.jpg .tif etc) in the file name at top of window. But then the subsequent format selections below third or fourth one read as the one above it in the list.
eg: as RGB file: Saving through BMP indicates same in file name at top (.bmp). However, the next choice below that, Gif, still shows as .bmp in file name at top. And so on to bottom of list. Same with CMYK file.
Never saw this in CS5.5.
When I initially installed CS6, I noticed only item in the Plugins folder was Panels folder.... no other plugins. I thought this to be a download error of some sort and dragged basic plugins from 5.5 into 6 Plugins folder. Could this be the problem? Otherwise, I would have NO plugins in CS6
I have downloaded CS6 twice now thinking the first was corrupted. I used both download options on Adobe page - Akamai and standard
Same issues with both. One response stated this all to be a plugins problem. I have uninstalled "after market" plugins from both 5.5 & 6 SuperBladePro was the only one. Restarted CS6. Still same problems. Only items in Plugins are what came with program.

Answer 1

I owe an apology to the previous responder Chris C, to this issue. I misread his solution thinking he meant I needed to delete ONLY the "additional" plugins like SBPro. Which I did. But rereading, I see he meant ALL the plugins I dragged from 5.5 because the 6 plugins folder was empty.
I thought it was corrupted in download. So if you guys get points for solutions, be sure Chris gets a few since I responded saying it did not work.
In fact, after removing the 5.5 plugins from 6, everything is working fine.
Plus I didn't know the 6 plugin folder was for the "after markets" like SBPro which is good to know.
Also thanks for the fairly quick response. I'm typically dubious about forums as troubleshooting solutions.
Kinda like sending a message in a bottle out to sea. Never know when it's coming back.
Sometimes issues are urgent. Your response team has encouraged me greatly  :-)
But still bummed that Chats do not support CS6 however.
