Yes, there is a core module (ip_vs), modules for schedulers,
for apps (ip_vs_ftp), persistence engines (ip_vs_pe_sip).

Yes but you can also use latest kernel from:
https://www.kernel.org/
You can also read some files from the kernel sources:
# When coding:
Documentation/process/coding-style.rst
# How to send patches in raw form:
Documentation/process/email-clients.rst
Documentation/process/submitting-patches.rst
# The final patch should be sent to addresses specified with
# 'M' and 'L' for 'IPVS' here:
MAINTAINERS
Knowing 'git' to create a patch is not required,
using such command to create your patch should be enough:
diff -urpN linux.orig linux
For user-space tool:
# get fresh ipvsadm sources:
git clone git://git.kernel.org/pub/scm/utils/kernel/ipvsadm/ipvsadm.git
to use --pe dtls

Yes. But more changes can be needed.

Yes, you can use such software. But initially you can
start with local real server and local client. IPVS supports all
4 cases:
1. local client + local real server
2. local client + remote real server (NAT)
3. remote client + local real server
4. remote client + remote real server
