That last line should be

  \transformfont{padro8r}{\slantfont{335}{\frommtx{padr8r}}}
                                               ^^^
since there (obviously) are no AFM metrics for padr8r.

That would be to combine the above, i.e.,

padro8r AGaramond-Regular "TeXBase1Encoding ReEncodeFont .335 SlantFont"
<8r.enc <padr8a.pfb

The "map file fragment writer" in finstmsc.sty (present as of v1.914) will
generate these entries if you tell it to.
