ok, first of all I would avoide mirical mud as this is not really for beginers to marines and is not straight forward.
as for biological media, i would use coral gravel as it is cheap and is porus. you could use something like efhisubstrat by eheim but there is no real need. you may need to use carbon periodically and i would definatly use rowaphos phosphate remover to keep the phosphate levels down. this can do in a small internal filter sat in the sump.
I would avoide trickle filters as they are a little out dated, and if your not carfull, they may tusn into a natrate factory.
you could do that with the pumps if you wanted its up to you.
I would not use fish to cycle the tank. I would get a few kilos of uncured live rock if anything and just forget about it for a month and leave the lights off for this period otherwise you will have a huge algea bloom. as for lighting you would only need a white and a blue tube for a fish only. have the white on for 8-10 hours and have the blue coming on 1-2 hours either side of that and leave it on all the time the whites are on.
clowns will not need an anenomy and even if you wanted one, you would need to wait at least 4-6, preferably 8 months before adding one and would need much better lighting.
as for rockwork, live rock is the best. this can be very expensive. you can either use all live rock, get some ocean rock and have a layer of live rock over it, or if you know anyone closing down a tank, you may be able to get some cheap live rock which is just as good if not better as the shop bought stuff.
you will not need to upgrade to have live rock, you can have it straight away.
you will need more light for coral, either metal halide of 4 T5's
I would leave out the anenomy.
as for cleaners, i'd go for hawian hermits and pleanty of them. these grow quite large and are quite hardy. if you want a "predatory" fish only tank with triggers, groupers, pufers etc, then you won't be able to have shrimps but if you want peacefull fish, then I'd go for some shrimps to and a red brittle star.
ste HATES to answer questions
why do you say that, i don't mind answering questions
ste
ooer is that 3000 per pump or in total as i plan to have two pumps just in case one packs up....was bad enough persuading the wife to let me have a marine tank....."It's no trouble pet honest" last thing i need is to flood the living room!! 
3000 per pump will also be fine 
its up to you what flow you want going through the sump.
