To buy LTC there are a number of different options. Assuming you're starting with fiat, you can get money into btc-e by US Bank Wire, EU Bank Wire (SEPA), Visa, Mastercard, Liqpay.com, unikarta.com, PerfectMoney.com, WebCreds.com, Ukash.com or Webmoney.ru.
Alternatively buy some Bitcoin (for example at Bitstamp or MTGox) and then transfer the Bitcoin to another exchange to exchange for Litecoin.
