@Butrflynet,
Okay, here's what I've compiled so far from my gardening links:
The Better Homes and Garden site has a wealth of helpful design and selection tools. They have pre-set garden plan suggestions to help get your creativity started. Take time to explore the gardening section of the site. There is a lot of depth to it. It has a plant selection tool to help you find plants for your climate. It also has a lot of do-it-yourself plans for hardscape projects.

They have some free online garden planner software that is easy to use.

I found this to be an easy planner tool too:

Another great magazine site is the Sunset Magazine.
They have a plant finder tool, landscaping and design tools and lots of project ideas.

This was one of the sites I found helpful in New Mexico. You can enter specific parameters and it gives a list of suggested plants to meet them. Don't be fooled by the title, they have plant selections for a wide range of climate zones.

What you might want to do is focus on planning and installing your hardscape projects this summer and use your downtime to browse through plant and seed catalogs to learn about plants and rip out pages for those you like and will grow in your climate. Collect them all in a folder and use that as a basis for selecting the plants for your various flower beds. Another idea is to find a local university extension and agricultural website for your area. They'll have lists of plant variety suggestions based on proven local experience.
Here's a list of catalog sites I've browsed through in the past and receive catalogs from. Most of these ship only to the US. If they specifically ship to Canada too, I'll mention it. All these places will send you a free catalog upon request.

They have a really good gardening calendar tailored to each climate zone so you'll learn when to do what. This was very helpful to me when moving to the arid climate of ABQ.
