Hey and welcome to the forum!
Photo's are a must (as mentioned!) Once you hit 5 post's (iirc) you can upload photo's to the gallery at the top of the page (clicky link in nav bar). Externally hosted photo's are a no no here on FF.
As for mods to your car the possibilities are endless. IMHO the biggest, single most important one, is lowering the GP. As they sit stupidly high as standard. Most common route people take is Eibach Sportlines (i've done this), they lower approx 35-40mm iirc and just remove that hideous arch gap. For this 17" rims look best IMO, 16's would work but are better suited to being dropped on your belly on coilovers.
Other mods are a matter of taste and opinion (yours more importantly). Ranging from window tints, debadged grill, mud guards, wind deflectors, carbon/plasti-dip subtle additions here and there. All up to you, a common phrase thrown about is "OEM+" (original equipment manufacturer) with the plus being that little bit 'extra' to turn your GP into every day stuff, to sweet stuff.
