Nylon strings are a good way start, You'll just nee to make sure they will work on your guitar. The string slots in the nut of your guitar may be to narrow if the guitar was set up for steel. Any music store could advise you whether or not they'd be a good fit. You may also want to consider using extra light steel. Keep in mind tho they will likley be more difficult to keep in tune.

As for choosing tabs, just look for tabs for music that does not sound complicated. Not knowing your musical taste it would be difficult reccomend anything.
