add four commas
Thanks for all the advice you gave me about China Thailand and Japan. I've now got all my books notes and translation guides. However, would you please give me a call this week regardless of the day or time as I do still want to pick your brains over the other thing we spoke about last Friday!

We should add a comma after the words "China", "books", "week" and "time", which totalizes four commas, as further explained below.

Where to add commas?

There are a few tips and rules when it comes to the use of commas in a sentence. We use commas to:

Separate items on a list.

Separate independent clauses.

Set off appositives and nonrestrictive clauses.

Distinguish the introductory phrase.

Separate phrases or words that interrupt the flow of speech.

Taking the rules above into consideration, we must add a comma after "China" and "books" in order to separate items on a list. We must also add a comma after "week" and "time" to separate phrases that interrupt the flow of speech or that are nonrestrictive.

Thus, the passage with the added commas would look like:

Thanks for all the advice you gave me about China, Thailand and Japan. I've now got all my books, notes and translation guides. However, would you please give me a call this week, regardless of the day or time, as I do still want to pick your brains over the other thing we spoke about last Friday!

In conclusion, the answer given above is correct.
