TinyMCE, update.php and links questions after upgrade to 4.7

HI all.

I just finished upgrading two sites (running off the same drupal code base), and things went pretty smoothly. If you're thinking of upgrading, make sure to watch the 4.6 -> 4.7 upgrade video...EXCELLENT! (http://drupal.org/videocasts/upgrading-to-4.7)

I have a few minor questions/problems.

1) I can't get the TinyMCE editor working anymore. I installed Drupal 4.7 in a different directory than where Drupal 4.6 was, and downloaded and installed the TinyMCE module for Drupal 4.7, enabled it, but I just get the default Drupal text area. (Yes, I downloaded and installed TinyMCE into the new 4.7 directltory and yes, it's enabled. :-)

2) How often should the update.php script be run? I ask because when you first run the update.php script to do the update, it specifically indicates not to run the update.php script more than once. However, click on Administer-->Modules, and just above the list of modules, it says "It is important that update.php is run every time a module is updated to a newer version." Ex. I was using the bookreview module in 4.6, disabled the module for the upgrade, then downloaded and installed the 4.7 version of the module for Drupal 4.7. I then enabled the bookreview module. Should I be running the update.php script again now, because of the new bookreview module?

3) After the update, I have "edit secondary links" and "edit primary links" links at the top of my page on one of the sites. Clicking on either one returns a "page not found". I know that there was a spot to edit the primary and secondary links in Drupal 4.6, but I can't seem to find it in Drupal 4.7. Where did it go? Or did it just go away?

Now that I've asked, I'll go search the forum to see if the questions have already been asked 100 times. :-)

Thanks all!
