No. Your kernel gets installed by "make install". Grub.cfg
will also be updated. After "make install", you're done and ready to
boot your new kernel. No need for further (grub) action.

https://www.kernel.org/pub/linux/kernel/v3.x/stable-review/patch-3.16.4-rc1.xz

The patches for the stable review are not showed on the kernel.org
main page, they live in the "stable-review" subdirectory as shown
above.

3.17 is the mainline kernel which is under actual development, and
will be the stable kernel once released and updated. Soon after 3.17
is released, the merge window opens, which is the time the developers
are sending new patches to Linus. After 3.18-rc1 is released, the
merge window closes, and usually only bug fixes are accepted then.
Important fixes will be backported to the stable kernel trees, thus the
different minor version number releases.

In short: the actual mainline kernel is the one which is most
up-to-date (3.17 will be released soon..).

With grub2, an additional "resume" boot parameter is not needed, as 
long as your swap partition is properly formatted (mkswap, swapon) 
and referred to in fstab when installing your kernel.
