You can skip the CD - it's just songs that help them remember some of the concepts, but it's not a critical component at all. I'll list the items I recommend, and why...
1. STUDENT WORKBOOK - self-explanatory (one per student)
2. TEACHER'S GUIDE - particularly important at the early levels when you're learning the HWT way yourself, but it also contains tips and ideas to make the lessons more interesting as well as a suggested schedule
3. SLATE - this is important for learning how to form the letters the HWT way, and if your DD needs to work on hand strength, this will be one of the most important pieces (but skip the chalk bits and sponge bits as you can make them cheaper). If you want to try to purchase a different slate for this task, make sure it's about the same size and proportion, has a frame (which helps in proper letter formation), and uses chalk rather than dry-erase or wet-erase markers. Chalk is key to the Wet-Dry-Try method used in HWT and will be particularly important for the repetition needed to develop her hand strength.
4. DOUBLE-LINE CHALKBOARD - the slate is for capital letters and numbers, but the double-line chalkboard is for everything else and is every bit as important for developing hand strength as the work with the slate. Outside purchases need to have a permanent double-line and be wide enough to write entire words rather than just one letter, but there is no real need for a frame on this one.
5. HWT DOUBLE-LINE PAPER - this reinforces the lettering habits learned in this method and is pretty important to have around for practice in the beginning, but once she's mastered the forms and is consistent, you can show her how to make the same letter forms on regular notebook paper or the three-lined paper that is popular in the lower grades (buy the smaller pack if you're not sure, unless you're working with more than once child).
As I mentioned above, the chalk bits and sponge bits are cheaper to make yourself from standard-sized chalk and normal kitchen sponges. Just stick to white or yellow chalk if you can, because the darker colors don't work as well for the Wet-Dry-Try method. I also didn't buy the short pencils because it was cheaper to purchase a small box of golf pencils. We weren't even done with those when DS was ready for regular-sized pencils.
The wood pieces were useful to us, mostly because they reinforced the strokes used for most letters, but they aren't critical. I was going to make them out of cardboard, but my husband made a set for me from the same material the company uses (woodworking is his hobby). You won't need them past the first grade curriculum anyway. Same goes for the capital letter cards. They're useful, but not critical, when working with one or two students - there is a picture on each capital letter page that shows how the pieces would be laid out if you really need to reinforce that, and cardboard or craft foam is plenty sturdy enough for a homeschool situation.
We skipped the sentence strips, the notebooks, and the CD. The CD is great for working with a larger group of kids in a classroom, but really isn't much value added. The other two are redundant components if you have the paper, and are more useful for classroom situations. If your daughter likes to write and illustrate her own stories or journals, it might be worth picking up a package of the notebooks to encourage that.
Let me know if you have any questions. HWT was recommended to us by an OT for similar reasons (DS needed to work on and strength and fine motor skills).
