first time inspection with repairs

[moenaboulsi]

I took my newly bought 2004 x5 4.4 for an oil change at a German car guy. I put 5w30 liqui-moly full synthetic. While at it, he did an inspection and showed me some things.

1) leaking transmission, said it was a plug housing. Quoted me to change that valvetronic plug housing, pan gasket and filter while Ian at it. 2.7 hrs@$90 an hr. Came up to $444. He said you have to use the same oil back.

2) front passenger cvs boot another 2.7 hrs came to like $350 or so

3) back frame bushings. One is not good, said you might have to change all 4
$90 each at 7.5 hrs. Around a $1000.

What do you guys think is priority? I really want to do the transmission because Ian not sure how much oil went drained. The transmission shifts smooth right now.
And what do u think of prices. This is in canada
