The Tang Monk, greatly pleased, put on his brocade-bordered cassock.
大喜 "greatly pleased." 錦襴袈裟 the brocade-bordered kāṣāya, the ceremonial robe a monk puts on for a formal occasion. He is dressing for an audience, which tells you how little he suspects.
Pilgrim took the passport-rescript, had Wujing bear the alms-bowl and Wuneng carry the tin staff;
捧著: 著 = zhe. 教 = jiào, having someone do something. 缽盂 "the alms bowl"; 錫杖 the monk's staff with its ringed tin head. Wujing and Wuneng are Friar Sand and Bajie under their religious names.
and the baggage and horse he handed over to the monks of Zhiyuan Temple to keep watch on.
將 = jiāng, taking hold of the baggage and handing it over. 行囊: 行 = xíng, travelling gear. 看守: 看 = kān, to guard or keep watch -- not kàn, to look at.
They went straight to the front of the Five-Phoenix Tower, made their bows to the Yellow-Gate officer, gave their names, and said they were monks of the Great Tang in the east, come to fetch scriptures and now here to have their rescript re-stamped, begging him to relay it within.
五鳳樓 the Five-Phoenix Tower, the great gate tower of the palace. 黃門官 the "Yellow Gate" usher, the official who carries messages in to the throne. 倒換: 倒 = dào. 煩為轉奏: 為 = wèi, on our behalf -- "trouble you to pass it up."
The pilgrims kit themselves out for a formal audience: ceremonial robe, travel document, alms bowl, ringed staff, with the baggage and the horse left in the temple's care.
Then they queue. They bow to the gate usher, give their names, state their business, and ask him to relay it. Every step is correct, and the care taken over the protocol is the point: the pilgrims are about to be attacked inside a system, and their only defence is to have used it properly.
