First, before you do anything else, check which version of the WRT350N you have. If you have V1, you're in business. If you have V2, you're outta luck.
Flashing a virgin WRT350N with the default Linksys firmware will require a special "trailed" mini-build to be flashed first. You should use a build from the BS Broadcom folder 12874 for the initial flash. The name of this file specifically is "dd-wrt.v24_mini_wrt350n.bin". You may proceed to flash it with a generic build next, such as Mega.bin. Remember to do the 30/30/30 Hard Reset after every successful flash. It is absolutely essential.
Do a Hard reset or 30/30/30 on your router. You will not get a password renewal page as you have stock linksys firmware on the router still.
Plug a cable into the lan port of the router and your computer, and disable any wireless to the computer. Disable all firewalls and virus protection. (Setting your computer to a static IP should not be required)
Set your browser to 192.168.1.1. This will open up the linksys webgui
Enter the username admin and password admin
Go to the administration tab. Click on firmware upgrade.
BROWSE to the dd-wrt.v24_mini_wrt350n.bin file you downloaded.
Click on the upgrade button and WAIT for the upgrade successful message. Wait at LEAST 5 minutes
Power cycle your router. (very important) WAIT until you can relogin at 192.168.1.1
Do another PROPER Hard reset or 30/30/30 on your router (very important) WAIT until you can login at 192.168.1.1
Click on any tab. Reset your username/password by TYPING in a new username/password
Configure your router
You can now upgrade to any generic dd-wrt build except Micro. Be sure to always do a hard reset prior to flashing another build, do a power cycle followed by another hard reset after flashing, and NEVER re-use a configuration file from a previous build or another router. Reconfigure from scratch.
Set your computer to a static IP of 192.168.1.7. (or to whatever subnet the router is on) Disable all firewalls and security. Disable wireless on your computer and only have the router connected to the flashing computer by the ethernet cable between the two.
Hard reset or 30/30/30 (If the router supports it, if not, reset to defults in the GUI) prior to flashing. Wait. Check for password page on re-login and change password.
Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
Wait...at least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
Wait for the lights to return to normal usually about 2 minutes.
Hard reset or 30/30/30 again (If the router supports it, if not, reset to defults in the GUI). Wait. Check for the password page and re-login to change the password. Then you can reconfigure your settings manually.
Once configured set your computer back to autoIP and autoDNS.
Important1: This Hard reset or 30/30/30 works fine for Asus router, but you do have to power cycle after the reset.
Important2: After you flash the firmware, and before you do the hard reset, the router will be building some nvram settings. YOU MUST WAIT FOR THIS TO FINISH PRIOR TO DOING ANYTHING WITH THE ROUTER INCLUDING A HARD RESET. Usually, you can tell when this process is completed by the WAN light coming on, but it does take several minutes. Go have a beer. There are starting to be more and more people who BRICK their routers by not waiting until the nvram is rebuilt, PRIOR to doing a hard reset. YOU NEED TO WAIT!

The USB port is where you can connect an external USB hard drive or flash drive. Which can do a multitude of things. You can use in as a NAS, storage for a FTP server, use Optware to run external programs like torrent software, samba for sharing files to your network, share a USB printer with your network... The list of possibilities is long, it just takes a little research.
ProFTPd is included in most the newer builds of dd-wrt. Check the features chart to be sure.
A ftp server, file sharing, and a media sever is included in TomatoUSB if your device is compatable.
