1.  How can I tell if I have Windows 7 64 bit or 32 bit?
2.  If I have 64 bit should I always install 32 bit apps or only 64 bit apps?  HOW DO I DECIDE?

I know I have Home Premium.  But that's all I know.

1) Go to control panel, click on System. The System panel will tell if you are using a 32 or a 64 bit version
2) Windows 64 bit has a nice feature called WoW64 that lets you run 32 application without problems: http://en.wikipedia.org/wiki/WoW64
If you have a 64 bit Windows it is better to run 64 bit application, obviously, but you will have no problems running 32 bt applications.

You want to make sure you have a 64-bit operating system because 32-bit can only support 3Gb of memory. Have more memory than that is useful indeed (4Gb minimum, 8Gb preferable). Looking the above panel will tell you as noted above.

It is not imperative that you use a 64 bit version of the OS. If your processor is a 64 bit processor it can still run a 32 bit version of the OS and also run 32 bit programs.
It ultimately comes down to your requirements.

I would recommend reading the official literature posted on Microsoft's website. Please follow these guidelines while making a decision.

Most 32-bit applications work fine in a 64-bit operating system. I have been doing that for about 7 years now. But I have had 8Gb of memory along the way. So 64-bit operating systems are better. Not imperative to your point, just superior.

8GB of RAM isn't the standard everywhere.  Most folks especially casual users of a PC or laptop still make do with much less RAM.
It needs to be mentioned that with 4GB of RAM there is little to no difference between a 32 bit and 64 bit OS.

As I've already mentioned a 32 bit OS and 32 bit apps can run on a 64 bit processor. There's no doubt about that.

@brothertruffle : Take a decision based on your current and future requirements and constraints.
