OK, I think your first priority should be something to cut lumber to size with. I know you are leaning toward hand tools but I would recommend some kind of power saw. A contractor's table saw or a high end portable circular saw would work. I also think a router would be a good power tool to have. You could do all hand work but I think rip sawing and routing are the two things that are much harder to do by hand tools alone.
Here are the first things I would say you need.
1. Table or portable Saw. Some people like a bandsaw but I like something that leaves a straighter edge for most work. The bandsaw is good is you do a lot of curvilinear or freeform stuff.
2. Good set of chisels, maybe Marples (Irwin) Blue Chips (cheap but a good value).
3. Router and table (you could make your own table and you can joint wood with it as well).
4. Good layout tools, an accurate combination square(Starrett), good ruler, good tape measure, pencils
5. Bench plane and block plane
6. A backsaw and a good small saw like a dovetail saw or a gentlemen's saw (sorry, that's what its called
7. Clamps (appropriate for what you intend to make)
8. Workbench (Tommy has a good affordable solution for this). This is a top priority.
9. A sharpening method (look up scary sharp in Google if you want to go cheap, Tormek is the Cadillac method)
Learn to sharpen first thing, probably tuning up those new chisels. Hand tools do not usually come out of the box ready to use so this is an important skill to have and will pay back by making your work easier and crisper. Learn to sharpen and tune up your plane. You can find these skills here and on the Internet.
My wife is just learning now and it was eye opening for me to instruct someone. Measuring and layout were something I did not think a lot about until I had to start with a beginner. Now I realize just how critical those skills are. Learn how to "square up" pieces using your saws and planes.
Find a good woodworking supplier. The big box stores are not going to have a lot of what you want. Online, you could try Rockler and Woodcraft if you have no stores close by.
Also, look at some of the projects here on the forum and see what tools the procedure list calls for. Buy them as you need them and it won't be as painful. Have fun and good luck. Ask us if you need recommendations on brand or type of tool. There is a ton of experienced knowledge here.
