You might find it easier to simply buy Bitcoins and then buy the Litecoins with Bitcoins from btc-e.com
Try localbitcoins.com. They are great for small amounts and you can even do escrow.
I can tell you buying bitcoins in the UK is nothing but simple. Therefore unless your lucky, prices here for bitcoins are 15% more or higher than GBP spot price, which kind of pisses me off.
btw noob question, what is escrow? I have heard it tons of times and i know its a type of encryption, but how does it apply to buying/selling btc?
I can see some on the front page now 7% higher than the spot price. Shop around. You'll always pay more than the mtgox rate on there though.
