Right, I will set up the positions to get things going, then I will let you chose your actions for the combat (remember to keep in character), I will also do a more detailed explanation of combat at the end of this post.

Floor plans:
Ground floor:
First floor:
The black rectangles on the walls are doors, the grey ones are windows.
The other darker parts are objects of some description 9some are labelled).
On the ground floor, the left room is a kitchen and the right is a lounge.
Upstairs, the left room is a bedroom, the right the baby's room with cot, and the last room (bottom right) is a toilet.
Combat:
Combat is broken down into turns, each lasting a second.
You may queue actions for up to 3 turns.
All actions can be given to me, and then I will carry them all out in the right order.
Here are the options available to you:
Attack (e.g. shoot, swing your knife)
Aim (adds your weapons accuracy score to the to hit roll, only works if followed by an all out attack).
Brace weapon (hold a pistol 2 handed, use a 2 handed weapon with a tripod or if you are prone, resting on a window sill etc. This adds 1 to your roll).
Aim for an extra second (increaes roll by 1 for every second).
All out attack (melee combat has three options, see below):
1. Determined (single attack at +4 to hit).
2. Double (make 2 attacks).
3. Strong (adds 2 to damage, or 1 per die).
All out attack for firearms gives you +1 to hit.
All out defence (i'll keep this one simple for you, it increaes your defence, but allows no attack).
Ready (pick up or draw a weapon, or a physical action e.g. close a door).
Move
Move AND attack (uses just one action, but decreases accuracy by 4, wastes all aims etc, and in combat greatly reduces effect).
Do nothing (name says it all).
Change posture (e.g. stand, prone, kneel).
Hope that helps, if you've got any questions, just ask

.
EDIT 1: Please specify where you are aiming (even if you don't use the aim action).
EDIT 2: Look at CG's actions, they are a good example.
