Respected mufti shahib..

1. I have a few questions in regard to zakat.
Say the nisab of zakat is $1000, and My wife has gold (which she doesn't wear) equal to $500 (throughout the year). She also have some land inheritade from her father, which has not been distributed yet and therefore it's not clear how many meters is her part.
On the other hand, I have some deposit money amount to $300 (the balance at the end of 1 year), a car which I use every day value to $3500, a house which I live in value to $5000. I have my salary but it always used up for our monthly expenses.
On the top of that I have some inheritance from my late father and mother in terms of land (2500 m2) and 3 houses . 1 house is in rental for $1600 / year, another house we rent the rooms to people, which gives profit (at the end of the year) of $300, and another house is just empty. These houses are supposed to be distributed among the three of us, but my brothers have not been able to do that yet.
Do we have to calculate zakat for each individual or can we combine both of our wealth ?
Which property is zakatable ?
How much do I have to pay for the zakat for each year ?
We really need your response asap as the time is getting close to pay the zakat..

2. Is khutbah for Ied the same as for jum'ah (2 times, with sitting in between). please explain the detail of khutbah for ied...
3. Do we have to pay income for our monthly income?

jazakallaah

wassalamu'alaikum wr. wb.
