As for security software... here are a few programs that can secure files for you. If you decide to get one, let us know how it works for you.
Data Protector 1.1
"Check files in, check files out. It's that simple. Once you've checked a file into Secure Storage, it disappears from view. Check in as many as you like, you're only limited by device memory. When you're ready to use a file again, check it out, and it becomes visible in the folder of your choice. Any kind of file is a candidate for security including: Word documents, Bitmap images, Excel spreadsheets, Powerpoint presentations, Text files, Pocket Notes, Jpeg images, Web pages, E-Books, MP3 files, and many more... "
Pocket Lock 2.14
"Keep your sensitive files safe! PocketLock lets you password protect individual files or entire folders using powerful encryption technology. And it's easy to use -- just select a file or folder, enter a password, and your data is safe. "
PocketPrivacy 1.08
"PocketPrivacy allows you to manage visibility of your private data on your Pocket PC device. With PocketPrivacy you can hide your personal private data: contacts, tasks, appointments, databases, document files, programs, voice recording files, images, photos, music files, notes, Pocket Word and Pocket Excel files.
