Hi Chic, Looks like everyone has answered your questions. The only additional suggestions I have are:
Have a BIN price on items so items are uploaded to google [I noticed a few of your listings only have bid prices].
Add delivery confirmation [DC} to your domestic packages so buyer can not claim 'undelivered' to paypal/google. You can add DC to all priority, parcel, and media packages. You can also add it to almost all first class packages/envelopes [I think the envelopes must be 3/4" thick...or something like that].
As for international shipping, I only use priority. It's expensive for the buyer but if it's small items, such as jewelry, I can combine shipping and help keep costs down that way.
Use the ebid shipping calculator on your items but be careful if package is over 12" x 12" x 12". Ebid's calculator does not operate correctly in those instances. See my forum re: this....

If you do offer international listings, do not offer it on low priced items. I found that paypal's fees are much higher on international transactions.
If you ship fragile items, make sure you insure them. I'm always amazed at seller's who put in their listings, insurance optional...buyer's responsibility. It is the seller's responsibility to get item to buyer so you're really insuring yourself not the buyer. If buyer pays via PP or Google and item arrives broken, buyer can just contact PP/Google or their credit card company to get their money back. So insure fragile items for your protection.
As for clothing, put measurements in listings. So many blouses, pants, etc. may have a size tag but what the buyer really needs to know is measurements. I don't know how many items I shopped in a department store and found I don't wear the same size depending on the brand.
I hope this helps. Welcome to ebid.
