Originally posted by tsweers89 What type of accessories should i purchase along with the camera?
For a total beginner I would recommend a K-x or K-r with the kit lens. I got a 50-200mm to pair with this and it's a bit cheaper than the 55-300. I seldom use the 200mm and usually use it at 135mm or less. Either option is good for a beginner, or wait and save up for something nicer.
If you are dead set on a white Pentax, then get one, you know you won't be happy with a black one. I recommend a white one with the kit lens. I remembered a seller on Amazon that used to bundle the K-x with the 55-300 and it looks like they still have them in stock for a reasonable price. Note that I've never bought anything more expensive than a battery from them, but they seem pretty legit:
Pentax K-x Digital SLR Lens Kit w/ DA L 18-55mm and 55-300mm Lens (White) | BeachCamera.com
or save a little bit of money and get the 50-200mm lens instead:

Originally posted by tsweers89 Like what type of memory card as there are many different types to pick from.
I recommend this one specifically, or another size (4GB, etc) from the same manufacturer. Don't skimp here.
SanDisk 8GB Extreme SDHC Class 10 Memory Card SDSDRX3-8192-A21
I have the exact same card, but I paid $50 for mine and it seems they recently dropped the price in half. They are the best in memory cards right now, super fast and reliable.
Originally posted by tsweers89 Filters, i have no idea what to even look for.
Don't waste money on filters, they just degrade your image quality. Some polarizers are nice for specific things but I don't recommend one for a beginner. Prevent damage to your lenses by being careful and always using a lens hood and lens cap. Pentax lenses also have good coatings on them that help a bit. Most of the filter effects from the 35mm film days are achieved in post production now. If you go to the beach or sandy/dusty areas frequently you should consider a UV filter to prevent particle abrasion, but this is a worse case scenario that I don't imagine the average person will encounter often.
Originally posted by tsweers89 A tripod would be nice but are the cheaper ones even worth it?
A cheap tripod would be better than no tripod. I picked up a half broken but still usable tripod from my local thrift store for $5 and haven't bothered to buy a new one yet. It needs to be functional enough that you trust your camera and lens investment not to fall over and break... Tripod is not required for a beginner unless you plan to mostly shoot landscapes and architecture.

You can pick up a generic cleaning kit for $5-20 all over the internet. Things I would look for are a lens cloth, lens brush, and particularly a rocket blower. I seldom need any of these things and went without them for the first few months I had the camera. Since you want everything up front and these are cheap so I'd buy a basic cleaning kit.
Good luck!
[edit]
Forgot to mention that if you go with the K-x you should buy and use rechargeable AA batteries. I like these ones so much I use them in all of my electronics now and have a couple of dozen of them in use now:
Sanyo Eneloop AA NiMH 4-Pack with AC Charger SEC-MQN064N B&H
You might also consider a camera bag of some type but those can be found anywhere.
