While I don't own a Teres I am intimately familiar with them. You do need a high mass stand though but I wouldn't let what you are using stop the purchase. The wall mount would be okay especially if it were of welded construction. Regarding racks, there are numerous ones to copy online. I built a rack for Audiogon member Vetterone. Do a member search and take a look at it. Adding doors and sides would have been easy.
I have strong opinions on the arms. Buy a Schroder. You'll never replace it unless you are going up Franks food chain. The entry level Schroder at $2200 with a carbon fiber arm wand is one of those "best buy in audio" pieces. You can mount a $10k cartridge on it and it will do the cartridge justice. In fact, we did that at a tonearm/cartridge shootout in Miami last month. I must admit the Triplanar is a stellar performer too.
I'm sure you would be happy using the Blackbird with any of these arms. I'm also sure that if you can afford it you will later get a better cartridge and a different phono stage. The Teres/Schroder combination will tempt you too much to upgrade.
I'll let others comment on the 265 vs. the 320. Vetterone has the 265 (plus Triplanar and ZYX Universe) and on the stand he uses it would be the end of the road for me. I've not listened to the 320. The 340 is bettered by the 360 enough that I would step up to the 360 if those were my choices.
