I think it is good insurance to get one to control the humidity of the area that stores your camera gear. It helps lower the risk of getting fungus growing on your lens. I just got my first dry cabinet after noticing two of my lenses 'kena' fungus.
Besides protecting your gear against high humidity, it also helps you to organise your equipment by keeping them in one area.
Filters for lenses
Many people say that filters (UV or skylight) protect your lenses from accidental damage or scratches to the front element. There are some who say that UV filters degrade image quality because of the flare factor (See here). There are yet others who say that the probability of accidental damage is slim and does not outweigh loss of image quality provided you take due care in handling your gear (See here). It depends on your usage and carefulness.
It's good that you are doing your research by asking questions here. Also try googling for recommended answers to your queries. It's important that you rationally know what is the reason for you to put on filters and what are the trade-offs. It's foolish to accept a simple answer like "put filters la, they protect your lens, rather change one filter than whole lens right?" You have to know what are the good reasons to do it. If not, you may be just spreading more misinformation next time you become 'old bird' and some newbie ask you the same questions.

Just something I wanna share with you:
I use two sets of UV filters for each of my glass for my 'photographic needs'.
One set is the really cheap shiny gray ones which I believe are made of just plain glass. I use this for street photography so I can introduce more flaring in my shots. Another set is the higher end Hoya Pro1D which I use for landscape and night shots where I don't want flares incorporated in the output. So far, it's doing the job.
For IQ degradation with UV on, I'm not really bothered (if there is) as I don't pixel-peep. Plus, I'm pretty much content with the sharpness of my outputs especially when using primes. But this I gotta tell you, my brother accidentally tripped on his tripod making it fall lens first towards a pile of rocks. Had it not been for the UV, he could've been recapitulating his budget for a new lens that day. Another is my cousin, hitting the nose of his long lens on a steel gate. Go figure what happened.
To sum it all up, I believe in the saying "You get what you pay for."; if you're too worried about IQ then go for really expensive ones. Cheap or not, just make sure you have one on the glass all the time. So it's up to you now. New filters or new lens?
(((It's just UV filters so what's the hoo-haa all about? Just do it and get it over with. It's not like you're gonna get abstract photos with them on.)))
Forget about the dry boxes. Unless you are VERY free, have a hygrometer and have time to monitor the humidity constantly.
The humidity can vary a great deal depending on the amount of sillica gel you place inside as well as the size of the box. And as mentioned PLENTY of times before, sillica gel is carcinogenic. You won't want to keep handling it.
Invest in a decent dry cabinet and save yourself all the hassle.
But to add, even if i were to use a good filter [hoya pro 1d, B&W] i would still take it off when doing long exposures and taking of scenery with tripod at night ...
Best for me would be just to get a lens hood, prevent flares and added protection
Buy Film Not Megapixels
A dry cabinet is NOT a MUST for your DSLR and lens because you can choose to
1. keep them in an air-con environment
2. migrate to a country with low humidity
3. shoot only in clean room environment
4. replace old lenses with new lenses every other year
5. use your camera and lens continuously for 24/7
6. use silica gel
7. use fungicide
8. enjoy the soft focus effect of fungus infected lenses
9. (someone said) keep them in the fridge
10. microwave you DSLR and lens periodically
Oh I forgot to add
11. irradiate your equipment with UV rays OR expose lenses to sunight everyday
Canon EOS 550D. 18-55mm. 50mm f/1.8 II.
Besides the $130, you forget the electricity bill ah?
I assume you are buying a 30L one. Maybe consider a 50L one? It's about $38 more and has free delivery, from my own buying search.

Can imagine yourself using a frying pan trying to heat the silica gels... and use a stirer to make sure it is heated evenly.
