No. You can boot directly from an LVM LV, and the installer will
set up a suitable initrd for you and configure grub to load the
kernel and initrd from LVM. As the above says, new distributions
support it properly.
If you have a complex setup (e.g. on RAID5), you might need a
separate /boot. If it's a single disc, it will work just fine.
If you're concerned, just create a separate /boot; it's not
necessary, but it doesn't hurt.

Yes. Partition manually, and create a partition to hold *all* your
Linux data. However, rather than selecting a filesystem type, you
choose "Physical volume for LVM", and then configure LVM. It will
then let you use this partition for a new LVM volume group. Once
that's done you can add as many logical volumes as you like, and
assign mountpoints to them, make swapspace etc, and then continue
with the install as usual.

I have no idea myself. I've always just used the tools directly.
