Cute! What happened to the job? I thought you'd just got there? (and btw, fingers crossed for the job in BFilmfans direction....)
The only way to succesfully "gypsy" yourself is to plan hard and long. Numerous reasons for doing this, but the main ones are that you know where everything is, and you don't need to buy duplicates of things you already have; just not with you.
Start making lists. (I suggest for ease of reference and mobility, you get a notebook for this; keep it with you at all times)
Depending on how long you're going to be mobile for, you may want to invest in some decent storage for your larger items. There's no point in carting around things that are not absolute necessities.
If you pack anything away into storage, number the crates, and put in the notebook EXACTLY which items are in which number crate.
For the items you need to transport, do the same with smaller boxes. In this case, lots of small ones are better than one or two huge - less to look through if you're trying to locate a specific item.
From the personal items point of view, try my tried and tested "pick it up and go bag" system. Large cosmetic bags are great for this - if you're not trying to co-ordinate colours its better, different colours, different uses. One bag just for washing (soap/facial wash/face cloth, toothbrush/paste/deoderant etc.) Another for showering (shower gel, body lotion, body glove, small deoderant etc) Another for hair (travel drier, mini shampoo, conditioner, styler, hair spray etc.) I'm sure you get the idea.
For emergencies, keep a set of clean clothes in a separate bag/holdall to the rest. If a case bursts open into a mudpuddle, you still have something to wear (and yes, it HAS happened to me!)
Anything of value (jewellry, keepsakes etc) leave with the bank/trusted friend/relation for safekeeping. Don't take anything valuable on the road.
I would seriously think about leaving the big tv behind - not only is there a liklihood of damage, it's probably going to take up more space than you need it to. And cat fur ain't that good inside tv's (speaking from experience here, too)
As for pusscat - before you even think of setting off, make sure the cat is chipped, if it isn't already. If it is, make sure the register has your cell number so they can always contact you.
You need to do a cat-bag too - emergency water in container, unbreakable food dish, resealable pack of treats, and a spare can of cat food/pack of dried food. Don't forget worming tablets and flea meds should be in there, too.
oh - and invest in a reflective collar. And a bell, if the cat doesn't object (mine did - used to fling collars across the room if they had bells on 'em!)
Keep your personal documents with you at all times, and find a safe place to stash any other items that would be tricky to replace. Depending on how long you're going to be on the road, you may want to consider making photocopies of important documents, i.e. passport, drivers licence, training certificates, cv, birth cert etc.
Bear in mind this is going to have to be done from a minimalist perspective - if you're travelling by car, remember you'll have to decamp everything from the car into your room for safety, every time you move location.
I'm still thinking on this, Cute, that was just basically a brain dump on my part. If I think of anything else, I'll be back! Let me know how you get on, though.
Best of luck

(Hey, just thought - you're having Xmas at home first, right?)
