Read a little already about bow mounted electric and it seems to be minn kota is the brand to use.
Would be using on my newly purchased 4.1dory, it has a 70ltr onboard fuel tank as well as 50ltr live bait tank, would normally fish with at least 2 in the boat as well so am wondering what size motor to go - 55lb or 80lb, and whether the ipilot feature is worth the money?

Don't have oodles of money to throw at this (hopefully around $1500 as I have a mate who works in the biz), the boat has a battery on board as it is electric start, it does recharge as the motor runs but I know little else, I'm assuming I might need to upgrade the battery and charging system but don't know how or what brands to use. Treat me like a novice please.....:-[

If you are into lure casting - you wont know yourself once you have a leccy. It seems that Minn Kota have improved reliability issues over the last couple of models ...... thankfully. They are not the only choice but they certainly offer the most features & are well served by BLA.
OK .... what motor ? - The 55lb would be ideal, If you can afford IPilot - get it ... everyone that I know who has it , raves about it! . ....... I would also get a foot pedal as a back up = specially if you plan to go away for holidays with the boat.
Battery set up ....... Firstly - You cannot have too many amps !!!!! - some will tell you stories of a 80amp battery lasting days (blah blah blah) - Just so you know , a 55lb Kota draws around 50amps / hour when run on full speed .......... so an 80amp deep cycle (lead acid battery) will be in the danger zone in 1 hour. If you troll in good conditions (little wind or tide) you'll get a couple of hours.
From my experience over the last 5 years - 100amp is the minimum (120amp is ideal) . I know you mentioned cost restraints but try to get the best battery you can get - for a leccy my starting point would be a Trojan 120amp lead acid battery ( somewhere around $250) = these are a robust long lasting battery & if well maintained (charged after using with a quality multistage charger) ...... you'll get many years out of it.
My personal choice is a AGM battery simply because they take a real pounding , maintenance free .... no acid to deal with . When I had my 24 volt system I had a pair of 100amp absorbed power AGMs which did nearly 4.5 years faultlessly & i'm still using them to run my engel when away camping. These cost about $400 each. ........ There are other choices like Remco , fullriver , lifeline etc . The downside is that the AGMs are expensive ..... so most people end up with only 100amps.
My new boat will have a 200amp running my 55lb MK ...... big battery (& costly) .
When it comes to charging ....... you can get an auto electrician to rig a Voltage Sensitive Relay (VSR) ... which basically switches the charge from the motors alternator to the leccy battery once the starter battery has been charged. From the research that I have done though - you need a big motor with a high output alternator & then be doing long enough runs to get the benefit - so dont bother. Just get a good 10-15amp multi stage charger like a Ctek & charge your battery after a days fishing. I have a 25amp C Tek as it pumps alot of charge in quickly ... which means I dont have to run a generator for half the night when I'm away and camping away from 240 volt power .

So that's about it ...... I'm sure you'll love the MK

From my perspective, which brand you use depends on the features you want. If you want a basic bow mount electric that does all you need, then save the money and buy a watersnake. They work fine and there are a hell ove a lot of them around and doing the business. If you like the idea of an IPilot, then go the minnkota. Agree with Chris above regarding size of motor and batteries.
