みなさん,こんにちは。

I was wondering what gramatical structure is best to use when asking for
advice as we would in English with 'Should I...?' Or 'should we...?'. I've
come across two possible choices but I'm not sure what nuance each structure
brings to the sentence. ' ーた ほう が いい です か' and 'ーたら いい です か'

What's should I use if I want to say these simple phrases for example:

  1. Should I take of my shoes?
  2. Should I open the window?
  3. Should we go to the cinema? 

My attempts:

  1. (私は)靴を脱いだほうがいいですか。
  2. 窓を開いたらいいですか。
  3. (私たちは)映画館へ行ったらいいですか。

Thanks in advance guys. よろしくお願いします!

question
grammar syntax
Asking for advice/suggestion "should I...?"
I’m Japanese naitive speaker and I don’t study linguistics.  
So I write my impression and opinion to your attempt.  

1「靴を脱いだほうがいいですか」  
This is correct and natural sentence because you have now two choices take off
your shoes or not.  

2「窓を[開]{あ}いたらいいですか」 I think this is a little bit unnatural. first, 窓を[開]{あ}いたら
is unusual. 窓を[開]{あ}けis natural.  
Now your choice is two 窓を[開]{あ}ける or [開{あ}けない. So I think 窓を[開]{あ}けたほうがいいですか？
is natural. this is just my impressions, there are possibilities that when you
say 窓を[開]{あ}けたらいいですか？ , a few people feel you are irritated. I think this
depends on your attitude and facial expression .  

3 Sorry, I can’t understand the situation so I can’t judge this is natural or
not. But In this case if you have two choice 映画館にいく or 行かない. So 行ったほうがいいですか is
more polite expression.  

P.S.  
I learned that my feelings that 窓を[開]{ひら}く is unusual is not common sense.  
This online Japanese dictionary says that 窓を[開]{あ}ける and 窓を[開]{ひら}く is both
used.
