I just bought an English saddle at my local tack shop, used, for $300, its in basically perfect condition as well! (riding my horse english and western now) So if your local tack shop sells used saddles, stop by and take a look. You can also try ebay, they have TONS of saddles. My saddle and bridle are not the same brand, and they look like they go perfect together. By boots do you mean human boots?
if so you should get a pair of paddock boots, western boots will not put your feet in the right position on an english saddle. I use a regular pad on my horse, like this: Riders International Quilted Cotton Saddle Pad - Dover Saddlery
And then a half pad underneath. Though every horse does not need a half pad. I use mine for extra cushioning and to raise the back of the saddle a bit. Usually saddles come as a saddle only. You will probably have to by the irons and leathers sepperatly.
Like these: Fillis Style Stirrups - Dover Saddlery
