I'm often stuck in situations in which I can't recall the correct grammatical structure or the appropriate words to use, and I fumble around searching for the right words to say. I assume the reason for this is that I've received insufficient input, and thus appropriate phrases don't come to mind when I need them. Therefore, it is important to receive enough exposure to common grammatical patterns and native materials so that appropriate expressions are naturally triggered when you need to use them in conversation.
I disagree with this, but it's only based on personal experience so it's not like I have any real evidence.
In my experience people who had never formally studied grammar and have never had their grammar actively corrected continue to make big grammar mistakes very far into the learning process even with lots of input. I have a friend who has passed N2, so he's fairly good at comprehension, but he still says things like 新しいの本 when he's talking, even though I wouldn't make that mistake even when I was around N4 level. Why? I took classes, unlike my friend, and when I did I had my teachers actively correct me when I made basic grammatical mistakes. Thinking about and understanding grammar will help you use correct grammar much faster than lots of input.
I think using the proper expressions at the proper times, however, is helped by input. However, it's also helped by understanding the expressions well when you first learn them.
Also, I believe that when you are searching for a word and you can't find it, it's because you don't have practice recalling the word. That is, you brain needs to make a path to recall the information during the production phase of a conversation, and the successful recall rate gets better the more you successfully use that word in conversation. Lots of input improves your ability to recall a word in active situations
very very slowly; practicing output and sometimes being able to successfully recall a word improves your ability to recall that word much more quickly. (As far as I know science about memory agrees with me on this point, so I encourage you to look it up--I should really get back to work so I'm not going to, haha. If you find that the science points the other way, let me know, but I'd be surprised.)
