As you already noticed, using a custom installer is bad. So why do you
want to do it anyway? You could just run the msi from your nsis
installer and be done.

And it appears that you have problems with the registry - basically
you're messing with things you admit you don't know what they're for or
what they're doing. Do you really think that's a good way to get a
properly working installer? You're risking a lot here...

Anyway: have a look at the WiX scripts we use to create the msi installer:
http://code.google.com/p/tortoisesvn/source/browse/trunk/src/TortoiseSVNSetup/StructureFragment.wxs

this one is the basic script required for TSVN. But I guess you already
have all the registry entries added from there. What you're definitely
missing is the registration of the shared Overlays component - that
component is shared by basically all TSVN clients now (TCVS, TSVN, THg,
TBazaar, TGit, ...). The reason all those other Tortoise clients also
use the msi for that component is that only msi provides reference
counting when installing components. It would be very bad if you
uninstall one Tortoise client and all other Tortoise clients would lose
their overlays because you didn't count how many Tortoise clients (or
other clients) are using that Overlay component.
So again, you see it's very, very bad what you're trying to do. There
simply can not be a good reason for this (no, your boss telling you to
is *not* a good reason - even if it's
http://en.wikipedia.org/wiki/Pointy-Haired_Boss).

But if you really want to break everything:
http://code.google.com/p/tortoisesvn/source/browse/trunk/src/TortoiseOverlays/TortoiseOverlaysDir.wxi
http://code.google.com/p/tortoisesvn/source/browse/trunk/src/TortoiseOverlays/TortoiseOverlaysDirx64.wxi

btw:
* those "ugly hexadecimal strings" are called GUIDs and are not ugly but
necessary, very useful.
* there are different GUIDs used for 32-bit and 64-bit installs
