The most conservative advice related to trademark marking usually consists of having an appropriate mark each and every time that the trademark is used.
What symbol can I use BEFORE the trademark is issued?

The ™ symbol, or a superscripted TM.
Can I add the ™ symbol to my website ?

Definitely Maybe. Trademarks do not protect websites directly. Trademarks protect consumers.
