Hii!
Yes! You need to remember the temperature conditions of certain reactions where they are necessary. This is because, certain chemical reactions are active at certain temperature conditions only. They will not take place under any different temperatures. So, temperature is important to remember.
If you find trouble remembering the reactions, write them down and revise them everyday, by their names. This is the only way to do so.
Also, if you understand the Mechanism behind every reaction and it's type, it becomes easy to make the appropriate products, thus, easy to remember the reaction.
Hope this helps.
Good luck!
