This answer is really dependant on your use. the first answer is clearly easiest if you have only one computer.
It doesn't matter. You could connect one USB & one Ethernet, Both Ethernet, Both USB. They have nothing to do with each other so they can be connected however you like.

If you have more than one device (Most of us do. PC, Xbox, Wii, BlueRay Player, Server, Iphone, Etc...) you will need to utilize an appliance. These appliances use Ethernet, and can only use one connection at a time. it is designed for fail-over. Another appliance can load balance but a single stream goes out a single connection and you can not exceeded the bandwidth of a single connection because your source ip needs to be the same. These provide a level of redundancy for traffic requests from inside the network.
There is minimal or no redundancy if you have an internal resource you need to access from remote.

Cisco ASA, Juniper Netscreen

Linksys RT04, Draytek Vigor 2910VG, HotBrick LB2, Netgear FVS124G

You can use a switch to connect different pieces of equipment. For example, a standard ADSL router only has a port for a single Ethernet cable. If you want to connect 2 or more computers to the Internet, you can use a switch. In this case, the ADSL router and each computer connect to the switch, via a standard Ethernet cable.If you don't have an Internet connection, you can still set up a home network to share files, etc. To connect only 2 computers, you can connect them directly via a crossover cable. To connect more than 2 computers, better use a switch.You can use a switch to connect different pieces of equipment. For example, a standard ADSL router only has a port for a single Ethernet cable.

The difference between internet service provided by ADSL and internet provided by cable is in the method of delivery. ADSL is high speed internet which is delivered through one's home phone. Cable is broadband internet delivered, as is stated, through cables.
ADSL
I believe your Internet Service Provider must sell you this option. Once you pay for it your router should be working at the speed of ADSL. I am currently using ADSL, but will be going to a faster speed.
No. A DSLAM is necessary to bridge the two modems.
If both have a network connection you can use a crossover network cable.
ADSL (asymmetrical digital subscriber line) is a protocol that you ISP (internet service provider) use it is a analogue signal. cable normally is a cat 5e or cat 6 in to the modem and is a digital connection (much faster)
Cable, Wireless, T-1, T-3, OC3, and Satellite internet connections all require a cable router instead of using an ADSL modem router to access the internet.
