The "source" of your package is on SRC_URI variable. you may point a git 
uri, or a mirror to you tarball.

you can have SRC_URI = "file://tarball.tar.gz" if you want

it depends on how you make your recipe PACKAGE_ARCH = "${MACHINE_ARCH}" 
says it's a package that only work for that machine, so it will be 
placed on tmp/work/machine_name. But, a lot of packages are commom for 
any architecture, for example ssh.

hum, you cannot. Please, use the checksums :D <3

(imagine that you know the source is trusted, but yocto need to 
"download" and "unpack" it, so you added 2 steps of "untrusted" behavior.)

yes, but only if you inherit autotools

bitbake mysweetheartpackage when you're developing should be enough.

If you want it installed on your image, you add it on your image install.

easiest/dirty way is local.conf CORE_IMAGE_EXTRA_INSTALL.
