small seq reads in GEO? how to map them?

[vebaev]

Hi all,
this is my first post here
And as slowly entering in deep-seq world I was wandering how to use a data in GEO datasets NCBI, for Example that one from Illumina:

http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM442932

Is downloading "full table" will dive me an untrimmed from adaptors pure reads ready for mapping or?
At the bottom they provide fastaq format but I think is untrimmed? and how to trimm adaptors if I do not know the adaptors seq?

Can I just "Download full table..." and map the seqs to reference genome?

As a finale goal I want/need to generate a GFF file with locations of these small RNAs
sorry for my newbies questions but I feel like a pin in the ocean of info

Thanks!
