No, its probably because if nobody knows the right answer (for sure)
they will probably not answer. But let me give you what I know.

There is no such thing as an enumeration represented as text.
They are always integers. The name equivalent you assign to the number
is for the benefit of somebody's source code or for the display on an NMS.
So what you have to have is:
param2 OBJECT-TYPE
SYNTAX INTEGER { stopped (0), ready (1), running(2) }
* Choosing the right ASN type

Here you asked two questions:
unfortunately, the agents I've been writing have been AgentX (using my Perl
and/or Java
sub-agent library, but...
1/ about integer32, I'd say use ASN_UNSIGNED, from my poor memory...
I don't have my reference information in front of me, but the differences
are:
- numbers from -2 gig to +2 gig
- numbers from 0 to 4 gig
- a things that are only allowed to 'increase'
2/ and the whole business of OPAQUE or float is true.
I don't believe there is a _real_ standard for floats, and OPAQUE is a way
to encode 'other stuff', but you can't count on it being usable anywhere
else, but in your code. Where ever I have needed something code
to a float, I redefine it as an integer to avoid the problem. I.e Instead
of saying 3.5 seconds, I use 3500 milliseconds.
In addition I am wondering about the agent mode MODE_SET_BEGIN. When

And since I can't speak intelligently about this... I won't.
