It is very bad practice to do this sort of thing in a panic.
You will almost inevitably stuff it up.
You need to back off and take several deep breaths, then approach it calmly and logically.

First of all, your Question 2 is actually Step 1.
You can do this in a loop:
for ifile=1:nfiles
matfile=[pth 'sub_' num2str(ifile)];
s(ifile)=load(matfile);
end

Now your Question 1 is Step 2:
save([pth 'allmyfiles'],'s')

where pth is something like: 'c:\PathToMyMatfiles\'
