11i to R12 upgrade preparation and guidance after multiple errors

Question

This seems like a nice place to get some help. The MOS help I have received so far hasn't been so great.
I am trying to figure out how to proceed from where I am right now. Here's what I have:
Project: 11.5.10.2 upgrade to R12
1) Successfully installed MW version 2.18 and completed the 1st four steps under the "Configuration" category (I have not yet laid down the R12 code tree)
- Tried step "1.6-Apply patch 7429271" and it failed:
--- The script being run is "get_from_url_1703_7429271.sh".
--- When running the script manually this error occurs:
--- "Exception in thread "main" java.lang.NoClassDefFoundError: oracle/support/mw/AruExecutor"
Needless to say it cannot download the patch.
2) I thought that I might install the LivePatch release 2.19 patch (12728371)
- I tried to install this patch using the "auto-install" method via "Configuration -> LivePatch" and recieved this error:
--- "The requested URL /pls/EOF/eof_manage_livepatch.main_page was not found on this server".
I think that I can install v2.19 manually if need be.
3a) Moving forward should I apply MW version 2.19 patch manually and try again with step 1.6? Is v 2.19 important at this stage?
3b) I can down download patch 7429271 manually but will further patch downloads fail? Should I insist on getting this issue fixed before continuing?
What is the best path for continuing?
Thanks, Chaz

**** Maintenance Wizard configuration Information ****
Protocol = https
Am I going to need to drop the MW schema and start all over or is there some way to change this dynamically?
Another thing that I noticed as part of the HTTPS selection is that it added these lines to these files:
listener.ora:
SSL_CLIENT_AUTHENTICATION = FALSE
WALLET_LOCATION =
(SOURCE =
(METHOD = FILE)
(METHOD_DATA =
(DIRECTORY = /up2001/R12/10g/102/eof/config/ssl_wallet)
tnsnames.ora
(SECURITY=
(SSL_SERVER_CERT_DN="CN=nwb-chi-tdb01.itciss.com, O=Maintenance Wizard, OU=Development"))
I don't think that they were there when I selected Protocol=HTTP.
