Getting back to your forge, these can be very nice if you get them running smoothly. I had one for several years a few decades ago, and used another for a while when I restarted blacksmithing a couple of years back. In the end, I found the pump lever on mine to be finicky and inefficient, so I first went with an electric blower jammed up the tuyere and later shifted to a JABOD.
That said, these can be great little forges, and you should definitely go ahead with what Frosty and CMS3900 said above. My only addition would be to check out what kind of wheelbarrow replacement handles your local hardware store sells. They are already pretty close to the right shape for the pump handle.
Regarding anvils, there are some great threads here on IFI about improvising one out of a piece of railroad track, a block of scrap steel, or even a chunk of granite. Take some time to read over those threads and see what inspires you.
I don't have any TBI myself, but there are those who have suggested it might be an improvement....
