My vote is with the consensus, decent clamps and material to build something.
Your post doesn't mention having a square or bevel gauge. Those are both inexpensive must have tools.
Before that, you might want to consider including your location in your profile information. You may live close to one of us who would be happy to let you test drive some of the tools we have accumulated. It would be a good experience for yourself to test drive someone's old Bailey, new LV or LN plane for comparison to know where you are with your plane tuning.
My other suggestion comes from your comment about being a tinkerer and tuning your own planes. If you are good and confident about fixing up the oldies that is a great way to increase the population of tools while saving money. If done carefully, you could actually make a few dollars on the tools you decide are not needed.
There are also a lot of good books on joinery and general woodworking. They are like tools, imagine what direction you want to travel and then look for the book that will help you arrive at that destination.
An LA Jack is a good plane, but it isn't something one absolutely needs. If my shoulder wasn't totally buggered from an accident, it may have never been considered for use in my shop. It is a great plane for use on a shooting board IMO.
It is always fun to spend other folks money.
