Would like to upgrade our system from OS X 10.5.8 to a more current one. Is that possible or will have to take into the Apple Store for assistance?

If your machine qualifies, you will need to phone an Apple Store and order the DVD. It is not available for download.
To add to roam's post ... you'll need to call your in-country online Apple store, not the local Apple store, which in the US is at 800-MY-APPLE, to order OS X 10.6, assuming your system is Intel-based with 1GB or more memory.
Requirements for OS X 10.6 'Snow Leopard'

Whilst Apple have withdrawn Snow Leopard from their stores, you can still get it from Apple by calling 1-800-MY-APPLE (if you are in the USA) and they will supply the SL DVD for $20 for a single user, or $30 for a family pack that covers up to 5 Macs. You can also purchase the code to use to download Lion from the same number (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:

If you are outside the US call your national Apple Helpline:

If you're in the UK, use this number: 0871 508 4400
When you have installed it, run Software Update to download and install the latest updates for Snow Leopard.
