I used this list several times last year and it's instinctive, but which made it relatively quick and easy. So here I'm just updating the list here. I initialised the hardisk this time first, after first running Super Duper! to back up all my files onto an external hardisk.
Run the Install OS X programme. [I chose to erase and install]
Customise - omit other languages and most printer drivers (avoid bloatware and save time).
Update some System Preferences: Date & Time, International: Format (Singapore); Input Menu: (uncheck keyboard pallete to remove US flag), Track Pad (activate settings and speeds).
System Preferences: Network (ctril-click Airport icon to set WEP 128-bit Hex password); Setup the NUS airport ID in a separate location and Singnet settings for 56k modem access and outdoor wireless.
Run the relevant Apple System X combo update (do not use Software Update)
Install Microsoft Office v.X 2004.
Apply the relevant Microsoft Office updates; it will tend to itself until complete.
Logout, then login.
Copy over from my backup hardisk, Entourage's Microsoft User Database and Projects folders into the Documents folder.
Copy over Documents backup
Install iWork '05.
Dreamweaver MX - install this web page WYSIWYG editor.
Shareware - Installing and register other shareware; go to web for downloads as these are the most updated versions. Extract the serial numbers data from my files.
Spam Sieve is critical for eliminating spam. Copy over the Spam Sieve folder (Library>Application Support) and the preferences file (Library>Preferences) from the backup hardisk.
Interarchy - ftp client that provides ftp mirroring and ftp droplets. First setup the ftp mirror for the Scratchbin where some data files needed for setting up are located.
Bookit allows me to extract my old bookmarks (Scratchbin) and update and synchronise all the browsers in a couple of keystrokes.
GmailStatus - keep tabs on mail in my gmail account by displaying a number on the menubar.
Copy Paste X - stores multiple clipboards so you can cut and past away at ease. Great when extracting all those serial numbers. Can also extract URLs from pages etc.
Drag Thing - allows me to assign shortcut keys to applications, and a series of docks that can store applications and bookmarks; adds version numbers to apps, allowing an easy check when upgrading.
Firefox - an alternate browser, now in version 1.0.3. I can install the Amazon A9 toolbar which also contains my bookmarks.
Camino - I'm a browser junkie, if one desn't work, some other will. I like the look andd feel of Camino and now in version 0.8.4 and looking serious!
Acid Search - provides drop-down alternative search engines in the google bar of Safari; critical for research of resources on the web.
Thunderbird - alternative email when I want to access the IMAP server in NUS on days when Entourage has not been synched with my desktop at the office. And for reading RSS feeds.
Adobe Acrobat 7.0 reader - resource hungry but I can't live without it yet. Remember to turn it off as the primary pdf browser plugin to allow the faster Schubart plugin to work. You still have the opttion to open pdfs in Acrobat so its the best of two worlds.
Quicksilver - when I type Cmd-space and the first few letters of an application, Quicksilver finds it and I can launch the application with the return key. It also works with bookmarks! - superseeded by Spotlight.
Rest of shareware - download when needed, e.g. VLC for viewing videos - well, if it is still available; it is threatened by EU controls.
Repair permissions - and run Disk Warior (3.0.3 at least for Tiger) and run through scripts in Cocktail.
