You don't have to have everything all at once. I only bout the xc boots in October, GK was in the open fronts for xc and sj for most of the year. If you are only jumping small jumps, it should be fine.
As long as you have the basics eg;
Horse - very important :)
Saddle - GP one is fine
Saddle blanket - you can use your white dressage one for all 3 disciplines
number holder - well we need these in Australia, anyway :)
Jacket - for dressage and SJ
tall boots/jod boots and gaiters
Everything else is optional, so don't sweat it if you don't have abosolutely everything. A good thing to read is the rule book, it should tell you what is required for each discipline as well as some points you may or may not be aware of.
