The "shorten the life" thing is vastly over-stated for recent generation SSDs.
Alignment should be OK by default, but you can check it with Diskpart in Windows.
Defrag should be off be default, but that can be set manually if needed.
You can move your page file to another drive if you are anxious about too much writing--but with 16 GB of RAM, you are rarely going to need a page file. Most people just leave it on the SSD and set it to maybe 1024 mb minimum or just let Windows manage it.
You can move your browser caches to another drive to reduce writes if concerned about writes.
The perceived "speed" of an SSD system comes primarily from its access times--which are circa 1/100 of the times associated with a spinning drive.
4-8 kb random write access is the single most crucial measurement.
You can enable write caching in Device Manager in the policies tab of the SSD.
You might put your default download folders on a spinning drive.
You can choose "No GUI boot" in the boot tab of msconfig to shave a few seconds off boot time. You should be able to boot in 30 seconds or so.
Samsungs are among the best current performers, so you shouldn't have any issues.
