Help with med-scale acoustic electric strings

[Chenzo]

Hello all, new guy here and couldn't find an existing thread for this on this forum, please forgive me if I've missed one.

I recently purchased a used Ibanez AEB10-BK acoustic-electric and am cleaning up the fretboard and replacing the strings. It's a medium scale, 32" from saddle to nut. I've never owned a bass of this scale, and I've never owned an acoustic bass before. I've been told that I need to use medium-scale strings only, though I'm having a hard time finding them specifically for acoustic bass. My questions are:

1) If that's what I need, anyone have a good reco on them, and know where I can find them online or around NYC or lower Westchester NY? (I just moved back and haven't found a favorite shop yet, didn't play much when I lived here before)

2) Are there reasons why I wouldn't consider using electric med-scale strings on it? This being my first acoustic bass I'm not assuming anything, though I've never done this on a 6-string acoustic guitar.

3) I'd like to use the same gauge strings that are on it now, and from what I know about the guitar it's still got the originals on it. Any way of finding out the stock size short of measuring with a caliper gauge? Ibanez has a chart that lists .045, .065, .80 & .100 for all their 4-strings, can I assume that this is true for their acoustics as well?

Thanks to all for any info, much appreciated.

GHS at one time made sets for both medium and regular long scale. I know that both www.bpstrings.com and www.juststrings.com carried them. Adamas also made a medium scale set. Check both websites. I have found Bob at bpstrings to be very easy to deal with on the phone and is very knowledgeable. He found me sets no one else could.
As for the second question, yes, regular medium electric strings will work on an ABG.
They won't be as loud acoustically, however.
