Welcome to the forums! Use a CPL (circular polarizer) to reduce glare and reflections and to increase contrast. Many other filters exist for various uses, but that is really all you need. You usually should NOT use more than one filter at a time. More layers of glass in front of the lens will hurt image quality. Look for a filter that is MC (multi-coated) to reduce flare. Cheap uncoated filters can also hurt image quality. Good luck!

CPL also removes glare making the colour of vegetation more vibrant for example and the sky deeper of colour.

A few other filters to consider:

A. Neutral density- somewhere between a 3 to 4 stop reduction to the exposure (ND 0.90 to 1.20). This will help you get to long exposure times when lighting is a bit bright
B. Graduated filters- Neutral density and warming (yellow and red) to balance exposure sky-to-ground and saturate the reds and yellows in sunsets. The square/rectangle ones are best for this so you can choose the transition zone.

With the use of the Circular Polarizer, this should take care of most everything, until you want some more special effects. Then the skies the limit!

Always look for good double multi-coated (front and back) filters. They cost more but reduce ghosting and unsharpness caused by it.

Regards,

There is NO optical need for a UV filter on a digital camera unless you are around 4500m / 15000ft or higher elevation. A Skylight or UV or clear glass filter can protect the lens against spray or sand or debris, but is otherwise useless. UV is already blocked in the sensor. Your most useful filter for handheld photography will be a CPL (circular polarizer) which is superior to a PL (linear polarizer).

And no, don't stack filters unless absolutely necessary. each filter in the chain degrades IQ by some amount. So you want the fewest number of filters that will solve the particular photographic you are having that causes you to consider a filter in the first place.
