hot swapping USB drives and install packages or ports from the CD

[Cecil]

Hello all,

I am a newbie to unix but have installed FreeBSD 6.2 with Gnome desktop 2.16.1 on my 
ThinkPad R40 and I have some problems:
1.  I can't connect to the Internet because my friend has dial-up with MSN and I can't get 
the moden to connect
2.  I would like to install Apache 2.2.4, PHP 5.2.3, and PHP-mysql 5.2.3 from my cdrom but I 
dont really understand the port system and the dependicies, whether I should download the 
Distfiles to a CD
3.  I have a USB stick drives that I would like to hotswap in and out --- when I boot they 
are there as /dev/da1s1 but will not return when I reinsert the drive in the usb port.

Thanks,

Cecil
