It saves the config to a file - usually, .config in the same directory as the 
source (/usr/local/src/linux/.config, for example). However, you can call it 
anything you please - just making sure that the file called .config (or 
symlink, whatever) is available for when you actually compile.

A common time-saver is to configure the kernel to your pleasing, and then 
saving the .config file somewhere safe. When you come to compile a new, 
later, version of Linux you can copy this file into your new source directory 
and do a 'make oldconfig'. This will then configure your kernel using the 
configuration you've provided, or using sensible defaults where your 
configuration is not up-to-date enough. So, it can be a one-shot deal for 
most common configurations :)

xconfig is fine. I personally use 'make menuconfig', which is practically the 
same interface, just using text. It's actually much faster to tweak a kernel 
config in menuconfig/xconfig, which you will no doubt want to do when you get 
into kernel compiling and start playing with things.
