the "when" phrase

I was just speaking japanese to myself to see how much I know (because i finished the excellent audio course)and I came across something... I dont know how to say "when" or "where" I think that when I go to Japan and get myself some japanese friends, this "when" and "where" phrase will be extremly helpful for me. For example. I am talking to a japanese friend and i want to ask: "when do you want to meet?" and then i want to ask "where do you want to meet?" How do i say these phrases in japanese?

Konnichiwa Soufiani! Ogenki desu ka? Yes, When and Where are very important words to know! Don't worry, it's quite simple. Here it is: "when do you want to meet?" *Itsu aimashooka? *or, more casually, *Itsu aooka? * "where do you want to meet?" *Doko de aimashooka?* or, more casually, *Doko de aooka?* Would do! Have fun in Japan! :D
