Have yourself get shot in the process so you don't attract attention. If you're a victim too, no one will ever suspect you.

err, this isn't possible because :

Spoiler:

Until Light discovers L's name, he is unable to kill him in any way... well no in such manners you described.

the Death Note cannot force one's death if this event will affect someone else, not mentionned in the death note.

that means : you CANNOT write someone's name, hoping he would assault the hotel, and shoots L.
Once you write a name in Death Note, that person will carry the order in such manners it is possible to that human to do so, without any possibility to kill anyone not involved in the process.
so : until that person is L himself, there is no way that Light can use someone to kill L. he has to kill L directly, there isn't any other way to do so.
