I see that most of your questions have already been answered.  One point
that I don't think was made is that in a 486 system, you must add memory in
sets of four modules.  That is, in your current configuration, you must add
another set of four 4MB or 1MB SIMMs.  You cannot add the SIMMs in a pair
as you could with a Pentium system.  I have seen 16MB 30-pin SIMMs
advertised sometimes but there are no 8MB 30-pin SIMMs.  This is because of
the requirement for installing memory in sets of four SIMMs.
