Here is what I have to edit the registry to change the large start menu color:
· Change Large Start Menu Color
ü [HKEY_LOCAL_MACHINE\SOFTWARE\HTC\EnlargeMenu]
i. "ManilaCustomHlUp"=dword:0049CE00
ii. "ManilaCustomHlDown"=dword:0049CE00
iii. Changing the color on each will create a gradient effect

As for the landscape issue, you need the landscape manila files. You might search for them and or try the following (this is what I would do next) using Total Commander:

1. Copy all the manila files from \Windows directory
2. Paste them into a new directory on your SD card or My Documents
3. Delete all the manila files in your windows directory
4. Soft reset
5. Copy the manila files in the new directory you created to the \Windows directory
6. Soft reset
