Upgrading Drupal

I have upgraded 4.7.7 to 5.2 drupal core successfully. Now I am working the modules, one at a time.

I am trying to get contemplate to render nodes correctly with the additional content added by other modules (book, location, etc.). There is a fix for this at http://drupal.org/node/93935 , but it only works with Drupal 4.7. I think I've isolated some of the changes that need to be made, but I'm not sure I've got all of them. This is a fairly small patch for the content module and the contemplate module, but it actually makes them work as expected (so this seems rather critical for either project).

I have noticed that there have been changes to hook_view() and hook_nodeapi($op = 'view') as described here:

Nodes are now prepared for display by assembling a structured array in $node->content, rather than directly manipulating $node->body and $node->teaser. The format of this array is the same used by FormAPI.

Modules that use hook_view() to prepare their custom node types for display should now use the following format:

<?php
function mymodule_view($node, $teaser, $page) {
  $node = node_prepare($node, $teaser);
  $node->content['myfield'] = array(
    '#value' => theme('mymodule_myfield', $node->myfield),
    '#weight' => 1,
  );
  return $node;
}
?>

Modules that use hook_nodeapi() to alter the node's content should use a format :

<?php
function mymodule_nodeapi(&$node, $op) {
if ($op == 'view') {

First)
After upgrading Drupal from 4.7 to 5.2, I cannot access directly to any node (such http://myserver.org/?q=node/17) if I log in to user mode. It sends me a blank page. But I can access to that page directly if I am in guest mode.

Second)
I also get this error after upgrading.

Before updating from 5.1 to 5.2, I decided to update some other modules including TinyMCE v1.0 2006/12/24 to the current version v1.7 2007/07/31.
When I went to www.mysite/modules I could not locate a folder called TinyMCE to upgrade, but instead found it in www.mysite/sites/all/modules/tinymce

Some of the pages on my site look fine; others are totally screwy, showing up only as plain text. I can't figure out why.

Pages that render properly include all of the following:
http://www.gettingintogradschool.com/poll
http://www.gettingintogradschool.com/purchase-getting-in
http://www.gettingintogradschool.com/reviews
http://www.gettingintogradschool.com/discussions

Pages which are screwy (i.e., show up as plain text):
http://www.gettingintogradschool.com/discussions/the-process-of-applying [or any other page in the "discussions" subdomain]
http://www.gettingintogradschool.com/book/getting-in-an-applicants-guide... [or any other page within the "book" subdomain]
http://www.gettingintogradschool.com/textlinkads/stats

I have recently migrated my site from one ISP to another (same 4.7 version). The process was a long, hard slog, so there's no telling exactly what may be causing this error. I did record everything I did, however, and if it becomes necessary, I would be happy to share.
