If it isn't obvious from what has been said, if you are paying cash, these expenses should be fine and will not likely create any problems. Keep receipts just in case the trustee wants to see them. If you charge these on a credit card, after you have begun planning for a bankruptcy, it could be construed as a nondischargeable constructive fraud, and that could be a problem. You cannot intentionally incur debt that you know you will not pay in advance of a bankruptcy filing. Hope this is clear, and good luck to you.
Why are you concerned that this would not be allowed? These are ordinary living expenses. As long as you are intending to pay for them, these transactions are irrelevant to the bankruptcy. To be confident in your bankruptcy planning, and prepare to file a problem-free petition, you should avail yourself of competent representation.

As noted above, these expenses are certainly valid. I would just add that it would be good to keep receipts and records of the transactions (don't pay your friend cash under the table for the work, essentially). You will be providing bank statements to the trustee, and they may ask for records if they see a lot of money leaving your account just before filing. The Seattle Chapter 7 trustees most likely won't have too many questions, if any, but it's good to have the records just in case.
Reasonable and necessary expenses are will not be questioned. If you charge them immediately before filing, there is a possibility that you will have to pay the amount back, but unless you are clearly charging with the intent to avoid paying, there should be no problem with getting a discharge on the rest of your debt.
