You are right about the conversion of a solar longitude into
any year's date. The J2000 tag behind all the lambdas denotes
the reference coordinate system; it is not the year the longitude
was taken from. It is sufficient if you know that the J2000
tag was there when you used a solar longitude, because then
the tables in http://amsmeteors.org/imo-mirror/solarlong/
are valid.
So take a solar longitude of a given shower, e.g. Lyrids 32.32
and look this time up in sol04.html and you'll gat a fair
estimate of the peak in 2004.
Best wishes,
