Okay, I figured it out on my own, it's not a manila file that keeps those settings, it's in the registry... here's an example

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\11]
"Enable"=dword:00000001
"Title"="[[IDS_PROGRAMS]]"
"PageName"="Manila://programs.page"

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\10]
"Enable"=dword:00000001
"Title"="[[IDS_SETTINGSTITLE]]"
"PageName"="Manila://settings.page"

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\9]
"Enable"=dword:00000001
"Title"="[[IDS_MUSICTITLE]]"
"PageName"="Manila://music.page"

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\8]
"Enable"=dword:00000001
"Title"="[[IDS_PHOTOSANDVIDEOS]]"
"PageName"="Manila://album.page"

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\7]
"Enable"=dword:00000000
"Title"="[[IDS_STOCK]]"
"PageName"="Manila://inforwidget.page"

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\6]
"Enable"=dword:00000001
"Title"="[[IDS_FAVORITEPEOPLETITLE]]"
"PageName"="Manila://people.page"

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\5]
"Enable"=dword:00000001
"Title"="[[IDS_INTERNETPORTALTITLE]]"
"PageName"="Manila://internet.page"

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\4]
"Enable"=dword:00000001
"Title"="[[IDS_WEATHER]]"
"PageName"="Manila://weather.page"

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\3]
"Enable"=dword:00000001
"Title"="[[IDS_CALENDAR]]"
"PageName"="Manila://calendar.page"

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\2]
"Enable"=dword:00000001
"Title"="[[IDS_EMAILTITLE]]"
"PageName"="Manila://email.page"

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\1]
"Enable"=dword:00000001
"Title"="[[IDS_MESSAGING]]"
"PageName"="Manila://messaging.page"

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\Configuration\0]
"Enable"=dword:00000001
"Title"="[[IDS_HOMETITLE]]"
"PageName"="Manila://home.page"

As you can see each tab is listed here, if you do not want one to show up just change ENABLE to 0 ("Enable"=dword:00000000). You list the order in absolute numerical order from left to right. I converted this registry entry into a cab so I can then run it in UC after flashing. It's rather satisfying when you can resolve an issue yourself

Just for kicks I changed HOMETITLE to 1 and MESSAGING to 0 and it worked!! My Home Tab is actually my second tab
