For the trial balance I don't know if I should enter any values under the accumulated depreciation and depreciation expense accounts.

Here are two of the transactions:

May 2: Night purchased a surround sound system and big screen TV with a digital satellite system for the guest lounge. The surround sound system cost $3,600 and has an estimated useful life of five years and no savage value. The TV cost $8,000, has an estimated useful life of eight years, and has a salvage value of $800. Night paid cash for both items.

May 4: Purchased the assets of a competing business and paid cash for the following: land, $100,000; lodge, $530,000; and fishing boats, $9,000. The lodge has a remaining useful life of 50 years and a $50,000 salvage value. The boats have remaining lives of five years and no salvage value.

For the depreciation value I got:
Fishing Boats - $1,800
Land - $100,000
Buildings - $9,600
Surround Sound System - $720
Big Screen TV - $900

I think I've calculated the depreciation value the right way, but now what do I enter under the trail balance for the accumulated depreciation and the depreciation expense accounts for each of these items?

Based on what you provided you do not have enough information to calculate depreciation because you do not have a date for the trial balance.

Both Accumulated Depreciation(credit balance) and Depreciation Expense(debit balance) is normally be listed on a trial balance, but might not be based on the information provided in your problem
