I have written some modules but I am getting issues how to get component item route.
For now I just put item ID in url, but this can't be my final solution.

see on the left side: pozejdon.h2.si (for example: special, last-minute atc. parameters)

Any idea how can I solve this problem, because I will read items from more tables and link them to more than one view.
Or even better, I slowly becoming like JDOM, how can I use JDOM in modules. I saw some post here on forum, but I do not understand how to implement, so simple tutorial, how to include JDOM and manually written SQL statements will be very nice

This is what I interested too. I have calendar module which filters my entries by day, month and year. When I turn on SEO generaly it works fine but the end of URL look like this:

example.com/en/component/component/view?year=2012&month=08&day=01

and other minor problems...

Well i learnt a lot with Lynda...

If you're ready to pay the small price, part of this tutorial is about making human readable urls.
Many other ressources available online, but nothing really simple.
