I was writing a letter to a friend in Russian, and got all mixed up with whether I should use perfect or imperfect tense. Say if you're discussing about something that's happening tomorrow, it should be in perfect tense, right? Like this-

Завтра они приедут - They will come tomorrow
встретятся они с детьми- They will meet with the children tomorrow

Another  question I have, say you want to say, I am going with his friends.

Я поиду с его дузьями.

should the word его also be changed to instrumental case?

no, the word его shouldn't change. Я поиду с его дузьями. - exactly complete!

Except for it should be Я поЙду с его дРузьями.

Завтра они приедут - It is correct

Они встретятся с детьми

Я пойду с его дузьями

When его means his (rather than him), it never changes form, so there is no instrumental version of this word.

Это он и его друзья. = This is he and his friends.
Подарки для него и его друзей. = Gifts for him and his friends.
Подарки подарили ему и его друзьям. = The gifts were presented to him and his friends.
Я видел и его, и его друзей. = I saw him and his friends.
Я пойду с ним и его друзьями. = I'll go with him and his friends.
Мне рассказали о нём и его друзьях. = I was told about him and his friends.

Future perfect:
Они сделают это завтра. ~ They will have done it tomorrow.
Они приедут завтра. ~ They will arrive tomorrow.

Future imperfect:
Они будут делать это завтра. ~ They will be doing it tomorrow.
Они будут приезжать завтра. Grammatically it's correct, but "будут приезжать" makes no sense in this case, because "приезжать" is a completed action by itself, but...
Они будут приезжать сюда каждое лето. ~ They will come here every summer, they will do it over and over again.

Present imperfect:
Они делают это завтра. ~ They are doing it tomorrow. They are to do it tomorrow.
Они приезжают завтра. = They are coming tomorrow. They are going to arrive tomorrow.

Future perfect:
Завтра они встретятся с детьми. ~ They will meet with (or just see) the children tomorrow.
Завтра я выучу испанский алфавит. ~ Tomorrow I will learn up the Spanish alphabet.

Future imperfect:
Завтра они будут встречаться с детьми. "Встречаться" (to meet, to come see) is the imperfect verb, but it implies more or less a complete action. You cannot "be coming to see" somebody all day long, so this sentence is grammatically right but logically wrong. However you may say:

Они будут встречаться с детьми каждые выходные. ~ They will come see the children every weekend.
Завтра они будут учить детей плавать. ~ Tomorrow they will teach children to swim.
Завтра я буду учить испанский. ~ Tomorrow I will learn Spanish.

Present imperfect:
Завтра они встречаются с детьми. ~ They are going to see the children tomorrow.
