Travel to Bahamas and reenter to USA with valid i-94 and expired visa

Hi, I'm an Indian working here in US with non-immigrant visa. My L1 visa was extended in US last year, so I do have a valid i-94 and expired visa in passport I would like to go to Bahamas/Mexico on cruise for 5 days trip. Please advise... 1) Can I go to Bahamas/Mexico with valid i-94 3) Do they really take my i-94 when I'm leaving US and entering to Bahamas/Mexico? 2) Can I reenter to USA with valid I-94 with a expired L1 visa in passport or do I need to obtain fresh L1 visa again to reenter to USA?
