Where to start

I partially disagree with this statement:
Ultimately, there are some fundamental similarities that you are likely already aware of.
1. The operating system manages the hardware.
2. The operating system provides an environment for applications to run in/on
3. File management and directory structures behave in a similar fashion
4. Scripts are written to manage mundane tasks
5. etc...
The uniqueness of the operating systems (whether Windows vs. UNIX vs. Linux vs. VAX vs. HP Calculator vs. whatever) are in how you manage various components as well as in how feature-rich your tools are.
Configuration in the UNIX world generally happens via the command line, rather than the extensive use of dialog boxes. In Solaris, you will be called upon to edit text configuration files. In Solaris, you have a 'cron' to manage scheduled tasks. In Solaris, your operating system is broken out into several directories (/var, /usr, /opt, /etc)
Any time that you expect to build a new host, you likely make a list of the services that you expect a host to provide - ie: account management, disk mirroring, secure file transfer, apache, etc. Do the same thing with your Solaris laptop. Focus on one area at a time, and play with configuring these on your laptop. Don't be afraid to get in and mangle stuff on your laptop. You can always reload the OS and try again.
If you are looking for a specific command, but don't know where to start (or what it might be called), you can check out the UNIX Rosetta Stone to get you started. Select "Solaris" from the list in the top left, then click "Draw Table". It has a bunch of commands grouped together by topic. Find one that looks related, and then go to your laptop and type "man <command>" (without the <>). 'man' is your friend - get used to it. It is our "clippy"
Once you are comfortable with some of the concepts - you don't need to know everything - then you can start asking some questions, and the nutshell book will help with clarity.

LAPTOP_MODE(8) System Manager's Manual LAPTOP_MODE(8) NAME
/usr/sbin/laptop_mode - apply laptop mode settings SYNOPSIS
/usr/sbin/laptop_mode [ cmd ] [ force ] DESCRIPTION
This manual page documents briefly the /usr/sbin/laptop_mode command. laptop_mode is a program that applies the settings given in the /etc/laptop-mode/laptop-mode.conf configuration file. The primary use is to control the laptop mode feature included in Linux kernels with versions 2.6.6 and higher, and 2.4.23 and higher. This feature increases battery life by letting your hard drive spin down. This is achieved by grouping disk write activity into "chunks" that are spaced at larger intervals than they normally would be. In addition to sup- porting the Linux kernel's laptop mode feature, /usr/sbin/laptop_mode also supports various power saving modules which are configured through configuration files in the /etc/laptop-mode/conf.d directory. It is not recommended to call /usr/sbin/laptop_mode directly to start or stop laptop mode, except in hardware event handlers. To apply new configuration settings from laptop-mode.conf, call the laptop-mode service init script with the reload parameter. COMMANDS
Specify force as the second parameter to force laptop_mode to re-apply a state even if the computer is already in that state. These are the values that are allowed for cmd : auto Enable or disable laptop mode based on the current power state. Note that this will not do anything if the laptop-mode service has not been started! status Display a status report about everything that laptop_mode affects. SEE ALSO
